Aim of work

To evaluate the role of ultrasound and color Doppler in diagnoses and predicting the outcome of necrotising enterocolitis patients at neonatal ICU.

Subjects and methods

Thirty neonates clinically diagnosed with NEC were examined, 51 ultrasound examinations were done including color Doppler sonography and findings were compared with laboratory data, clinical picture, staging, abdominal radiography and patient's outcome.

Results

Bloody stools and abdominal discoloration correlated with highest risk, low PH and neutropenia and increased DAAS score matched poor outcome. echoegnic free fluid, thin bowel wall, absent wall perfusion, aprestalsis, dilated anechoic bowel, increased bowel perfusion and pneumatoses intestinalis matched adverse outcome. sonographic signs of pneumatoses intestinalis interrelated with radiographic signs.

Conclusion

US was found to be highly sensitive and specific in diagnosing, staging and predicting the outcome of NEC patients, based on group of findings that were categorized per their risk ratio and correlated with outcome.  相似文献

Aim of work

To assess the role of color Doppler ultrasonography and multidetector computed tomography angiography (MDCTA) in diagnosis of uterine arteriovenous malformations (AVMs).

Methodology

Twenty patients were referred to the radiodiagnosis and imaging department, faculty of medicine, Tanta University from obstetric and gynecology department. All patients were suspected clinically to have uterine arteriovenous malformations. All were subjected to history taking regarding clinical state, laboratory investigation and color Doppler ultrasonography and multidetector computed tomography angiography of the pelvis.

Results

Color Doppler ultrasound sensitivity was 100% in detecting a uterine hypervascular lesion and highly suggesting the diagnosis of uterine AVM and the sensitivity of MDCT angiography was 100% in diagnosing and evaluating uterine AVM.

Conclusion

Doppler US can strongly suggest the presence of AVM but patient should undergo CT angiography for definitive diagnosis and possible embolization, as CTA helps in providing valuable cross sectional anatomical details about the lesion, its extent and its surroundings.  相似文献

Objectives

To assess pretreatment endometrial abnormalities in newly diagnosed, nontreated histologically documented breast cancer patients using sonohysterography and MRI diffusion.

Methods

In a prospective study, 45 women with histologically documented newly diagnosed non treated breast cancer and abnormal endometrium was detected by transvaginal and/or abdominal US, sonohysterography and MRI diffusion was used for further characterization of the type of endometrial lesion (non-pathologic endometrium, endometrial hyperplasia, polyp, sub mucous myoma, or malignancy). Results compared with final histopathological diagnosis reached by hysteroscopy, endometrial biopsy or surgical findings as gold standard.

Results

Transvaginal and/or abdominal US showed an abnormally thick endometrium in the studied non treated breast cancer patients, sonohysterography and MRI diffusion were done for all patients. The diagnostic performance of sonohysterography for 3 main endometrial abnormalities (i.e. endometrial hyperplasia, polyps and submucous myoma) was 95%, sensitivity, 90% specificity, 89% Positive predictive values, 94% negative predictive values, and accuracy 95%, while MRI diffusion with ADC cut off value1.15?×?10?3?mm2/s, showed 96% sensitivity, 94% specificity 98% negative predictive values and 99% positive predictive value and accuracy 91%. Best results were seen in cases of submucous myoma where sensitivity and specificity of both techniques reached to 100%. There was 91%, 93% agreement between HSG, MRI diffusion and histopathological results respectively (p?=?0.002).

Conclusion

High incidence of occult endometrial lesions in breast cancer patients in dependent of tamoxifen therapy, suggests pretreatment endometrial assessment.HSG is accurate in discrimination between focal and diffuse endometrial lesions, and help making a decision for either hysteroscopy or directed biopsy, but cannot reliably differentiate benign and malignant lesions.MRI DWI is accurate noninvasive method in distinguishing benign from malignant endometrial lesions which need further evaluation by biopsy.We recommend that HSG can be used as an initial investing technique in cases of endometrial abnormalities, however in cases of failed HSG or biopsy, MRI diffusion can provide an efficient alternative tool to exclude malignancy.  相似文献

Background

Uterine tumors are considered one of the major, causes of death. Detection, characterization and staging of these tumors, remain the cornerstone for proper management.

Objective

Describe the, various uterine tumors at DWI and assess its ability in, detection, characterization and staging of these tumors.

Patients & methods

This study included 25 patients with suspected endometrial and, cervical masses between June 2015 to December 2016.These were referred from, the ultrasound unit to the MRI unit of Radiology Department for further, characterization and staging of the tumors. All patients were evaluated, with transvaginal ultrasound and only those with suspicious masses were, included in our study. Conventional MRI with DWIs was done. All images were, analyzed as regards the degree of signal intensity and interpreted into a, quantitative measurement using the ADC mapping. This was followed by, staging of tumors using FIGO staging. The sensitivity, specificity and, diagnostic accuracy of DWI with the ADC cut off value in each malignancy, were calculated.

Results

DWIs with ADC maps showed a sensitivity and, specificity of 80% in endometrial cancers, sensitivity of 87.5% and, specificity of 100% in cervical cancers. The mean ADC value for, endometrial cancers was 0.8?×?10?3?mm2/s and 0.6?×?10?3?mm2/s for cervical, cancers.

Conclusion

Conventional MRI findings in conjunction with DWI and, quantitative measurement of the ADC are effective methods in the, diagnosis and staging of uterine cancer.  相似文献

Purpose

to evaluate the role of three dimentional power doppler ultrasonography (3D PDUS) of the uteroplacental circulation in early pregnancy as a screening tool for prediction of preeclampsia.

Patients and methods

50 pregnant women who came to do routine ultrasound scan between 11 and 13.6?weeks of pregnancy during the period from February 2016 to April 2016. Placental volume and vascularization indices were obtained, and vascular index (VI), flow index (FI), blood vessels and blood flow index (VFI) were calculated by three-dimensional Doppler histogram.

Results

Of the included 50 pregnant women, 22% developed preeclampsia and 78% did not develop preeclampsia. The placental blood flow perfusion in patients with pre-eclampsia had a lower VI, FI and VFI compared to non preeclamptic women with highly significant statistical difference (P?<?0.001)

Conclusion

3D PDUS can be used as an effective screening tool to predict preeclampsia in early pregnancy.  相似文献

Purpose

To compare the role of ultrasonography and MRI in the diagnosis of synovitis involving wrist and hand joints in Rheumatoid arthritis patients.

Materials and methods

Fifty patients with rheumatoid arthritis involving the wrist were subjected to hand and wrist ultrasonography Doppler and MRI and the results are compared and correlated during the period from December 2015 to January 2017.

Results

Ultrasound detected synovial hypertrophy (pannus) in 42 wrist joints while MRI detected it in 46. Power Doppler detected increased vascularity within 30 wrist joints (60%), MRI detected synovial enhancement within 38 (76%). Power Doppler detected synovial activity (vascularity) in MCP joints of 13 patients and MRI detected synovial activity (enhancement) in MCP joints of 9 patients. Ultrasound detected erosions in 35 wrist and 27 MCP joints and MRI detected erosions in 37 wrist and 25 MCP joints. Ultrasound detected tendinitis in 9 extensor tendons and MRI detected tendinitis in 8 tendons.

Conclusion

We found a significant correlation between power Doppler ultrasonography and MRI in the detection of signs of inflammation and bone destruction in the wrist and hand joints in rheumatoid arthritis, which raise the potential importance of power Doppler study in the assessment and monitoring of disease activity as a reliable non-invasive method.  相似文献

Purpose

To evaluate the role of ultrasound elastography, Doppler and micropure imaging in the assessment of thyroid nodules, using the pathological analysis as the reference standard.

Patients and methods

A prospective study was carried on all patients referred to radio-diagnosis department at Tanta Cancer Centre between November 2015 and November 2016 for evaluation of undiagnosed thyroid nodules. All patients were examined by B-mode ultrasound, color Doppler, micropure imaging and ultrasound elastography. All thyroid nodules were subjected to fine-needle aspiration biopsy.

Results

90 patients (78 women, 12 men) with 159 incompletely diagnosed thyroid nodules. 24 nodules were malignant and 135 nodules were benign, micro calcification was detected by micropure imaging in 40 nodules (29.6%) in the benign thyroid nodules and in 20 nodules (83.3%) in the malignant thyroid nodules (sensitivity 83.3%, specificity 70.4%, and accuracy 84.9%). Color flow Doppler (type III) with marked intranodular and absent or slight perinodular blood flow, was detected in 19 malignant nodules, with sensitivity 79.2%, specificity 95.6%, and the overall accuracy rate was 88.7%. The predictivity of ultrasound elastographic score measurement has high sensitivity 87.5%, and specificity 91.1%, Strain elastography cutoff value for malignant nodules was 2.7 (Sensitivity 83.3% and specificity 91.1%).

Conclusion

Elastography and micropure imaging technique are useful imaging modalities to detect the nature of thyroid nodules. In combination with Doppler and B-mode sonography, they could give a better assessment for undiagnosed thyroid nodules.  相似文献

Purpose

To highlight the relationship between coraco-humeral distance and subscapularis tendon tear.

Material and methods

Sixty-two shoulder MRI studies were examined. Twenty-two patients had partial or complete tear of subscapularis tendon and forty shoulder as a control group. Axial and oblique sagittal MR images were examined to measure the coraco-humeral distance followed by statistical analysis to correlate the distance with tendon tear.

Results

A cut-off value of 8.25?mm for the coraco-humeral distance gave a sensitivity of 77.5% and specificity of 72.7% for subscapularis tendon tear.

Conclusion

There is a well-known relationship between the coraco-humeral distance and the subscapularis tendon tear and its meticulous assessment in subjects with pain in the anterior shoulder region increases the diagnosis of subcoracoid impingement.  相似文献

Purpose

To evaluate the role of 3-dimensional (3DUS) and 4-dimensional ultrasound (4DUS) in detection of fetal causes of oligohydraminos.

Patients and methods

250 pregnant females (Age range from 19 to 45?years, mean age 33?years) were referred from the Obstetrics and Gynecology Department with oligohydraminos for fetal anomaly scan and Doppler study.

Results

111 of the 250 patients were primi- gravida and 139 were multigravida. Consanguinity was positive in 106 females. In 100 patients, the examined fetuses were abnormal, TORCH infection was +ve in 25 patients. In 150 cases no fetal cause was detected for oligohydraminos. Autosomal recessive polycystic kidney disease (ARPKD, Potter type I) was the commonest fetal cause in our group detected in 24 of 100 patients followed by bilateral multicystic dysplastic kidney (Potter type II) in 19 patients, unilateral renal aplasia was the least cause in our study.

Conclusion

3-dimensional and 4-imensional ultrasound and anomaly scan are effective in detecting fetal causes of oligohydraminos and early determination of lethal causes.  相似文献

Aim and objectives

To evaluate the diagnostic accuracy of elastosonographyin prediction of malignancy in solitary thyroid nodule.

Methodology

60 patients (37 females and 23 male) with solitary thyroid nodule were included, their age ranged from 21 to 52?years (mean age 30.6?years), grey scale, color-power Doppler US and elastography were performed for all patient.

Results

Presence of hypoechogenicity, absent halo sign, irregular margins, microcalcifications and predominant intranodular vascularity were the most US patterns predictive of malignancy. Suspicious nodule by elastography (Astria score 3 and 4) were found in 19 nodules (31.7%), 9 of them were benign and 10 of them were malignant with sensitivity 58.82%, specificity 79.07% and accuracy 73.33%, combined suspicious US findings (TIRAD 4&5) and suspicious elastography score (3&4) were most predictive of malignancy which was found in 16 out of 17 nodules with sensitivity 94.12%, specificity 76.74% and accuracy 81.67%.

Conclusion

Combined gray scale, color Doppler US and elastography were more sensitive and accurate than US features alone in prediction of malignancy of solitary thyroid nodules with sensitivity 94.12%, specificity 76.74% and accuracy 81.67%.  相似文献

Objective

To assess the role of multislice computed tomography (MSCT) in the diagnosis of mesenteric vascular occlusion.

Patients and methods

This study was performed on 30 patients clinically suspected and radiologically confirmed to have mesenteric vascular occlusion, they were examined with 64 row MSCT and were evaluated for evidence of bowel wall changes and abnormal mesenteric vascular changes.

Results

We found that the most prevalent MSCT findings were bowel wall thickening followed by diminished wall enhancement. MSCT gave an accurate diagnosis of the cause of mesenteric vascular occlusion as proved by the final diagnosis based on surgical exploration, laboratory investigations and clinical follow-up.

Conclusion

MSCT is accurate, fast and non invasive technique which should be used in clinically suspected patients with MVO in order to confirm the diagnosis, identify the aetiology and in addition assessing the bowel loop status for adequate management with good prognosis.  相似文献

Objectives

To evaluate the reliability of diffusion-weighted imaging (DWI) in evaluating kidney changes after extracorporeal shock wave lithotripsy (ESWL) treatment for kidney stones.

Patients and methods

This prospective study included 28 patients who subjected to ESWL treatment for renal stones. Color Doppler ultrasonography (CDUS) and DWI were achieved before and within one day after ESWL. Follow up DWI also performed 2?weeks after ESWL. DWI was performed with b factors of 0, 500 and 1000?s/mm2 at 1.5?T MRI. For each patient, the Resistive index (RI) and ADC values were calculated for both the affected and contralateral kidneys.

Results

The ADC values of the treated kidneys were lower in all three poles of the kidney compared with ADC values done before ESWL and in comparison with the contra lateral un-treated kidney. The RI showed no significant difference in the three poles of treated and untreated kidneys before and after with ESWL (p?>?0.05).

Conclusion

DWI is a reliable method in detecting renal changes after ESWL treatment that can give prediction about kidney changes produced by shock waves.  相似文献

Objectives

To evaluate accuracy of computed tomography angiography (CTA) in evaluation of post traumatic renal vascular injury.

Patients and methods

38 patients were presented with post traumatic intermittent or persistent hematuria. Renal CTA and digital subtraction angiography (DSA) were done for all patients.

Results

CTA demonstrated pseudoaneurysm (PA) in 30 patients (78.9%) and no vascular lesions in 8 patient (21.1%). CTA had 86.11% sensitivity and 50% specificity in detection of post traumatic renal pseudoaneurysms, CTA missed diagnosis of renal arteriovenous fistula (RAVF) in 10 patients which discovered later by DSA.

Conclusion

CTA with MIP as non invasive technique widely replaced renal DSA in detection of posttraumatic renal pseudoaneurysm. Renal DSA is still best modality in detection of RAVF and also has the upper hand in planning of selective renal artery embolization for the management of persistent or delayed hemorrhage from renal vessels.  相似文献
