Objective
Our aim was evaluate the role the PET/CT in the assessment of response to therapy in patients with Non-Hodgkin extra-nodal lymphoma: in particular, a five-point scale (Deauville criteria), which can be employed for early- and late-therapeutic response assessment.Methods
Sixty patients with pathologically confirmed Non-Hodgkin lymphoma (NHL) were enrolled in this prospective study. All patients underwent the following PET/CT examinations: initial PET/CT for staging, interim PET/CT and end of treatment PET/CT. Response assessment was done using new Cheson’s guidelines and five-point scale (Deauville criteria).Results
All patients were evaluated for response to therapy in the early interim, followed by late interim, as well as end treatment assessment for the overall response. We found good concordance of response assessment according to the Deauville criteria classification with International Harmonization Project (IHP) classification. After early interim 48/60 patients had concordant designations (91.7%, 83.3%, 70%, and 33.3%) and 12 patients had discordant designations. After late interim, 56/60 patients had concordant designations (100%, 100%, 80%, and 50%) and four patients had discordant designations. After end of treatment, 54/60 patients had concordant designations (100%, 100% and 71.4%) and six patients has discordant designations.Conclusion
Response assessment according to the Deauville criteria classification showed good concordance with IHP classification. According to our findings, we recommend the use of Deauville criteria in reporting of PET/CT for staging and assessment of response to treatment. 相似文献994.

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995.

Objective
Evaluate adding MRI to ultrasound in imaging of placenta previa with suspected placenta accreta.Patients and methods
evaluation of 23 pregnant females presenting with placenta previa was done. The age ranged from 20 to 39?years (mean?=?30.9). All of the patients were subjected to ultrasonography (US) and magnetic resonance imaging (MRI) of the pelvis at gestational age of 25–37?weeks prior to elective delivery.Results
11 out of 23 patients were proved placenta accreta based on surgical and pathological reports. US suggested diagnosis of placenta previa/accreta in 8 patients and placenta previa without accreta in 15 cases. 7/8 was true positive (87.5%) & one was false positive (12.5%) with sensitivity 63.64%, accuracy 78.26%, and specificity 91.67%. MRI has suggested diagnosis of placenta previa/accreta in 8/23 & placenta previa with no accreta in 15/23 patients. MRI was found to give true positive results in 8/8 patients proved to be accreta. MRI gave true negative in 12 patients (80%) & false negative in 3 (20%) with sensitivity 72.73%, accuracy 86.96%, and specificity 100%.Conclusion
Combining MRI and ultra sound provide more diagnostic information and may reduce unnecessary interventions with favorable outcome. 相似文献996.

Purpose
Our aim was to evaluate the utility of diffusion tensor imaging (DTI) in exploration of white matter tracts microstructure changes and clarify their relation to episodic memory in temporal lobe epilepsy (TLE).Materials and methods
DTI was performed on 30 (18 left, 12 right) TLE patients and 20 healthy controls. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were calculated for six fiber tracts; the parahippocampal cingulum (PHC), superior longitudinal fasciculus (SLF), inferior longitudinal fasciculus (ILF), fornix (FORX), uncinate fasciculus (UF) and corpus callosum (CC). Assessment for episodic memory (visual and verbal) was performed at least 48?h after the last seizure.Results
All TLE patients had episodic memory impairment. Left TLE patients demonstrated more verbal memory affection, whereas right TLE patients demonstrated more visual memory affection (p?<?0.05). Abnormal DTI parameters (decreased FA and increased ADC) were detected in most of the white matter tracts (p?<?0.001) compared to control group. In left TLE patients, there was significant correlation between DTI parameters of left (PHC, SLF, UF, FORX) and verbal memory. Whereas, in right TLE patient, we found significant correlation between DTI parameters of right ILF and visual memory.Conclusions
TLE patients had multiple micro-structural white matter tracts abnormalities and episodic memory impairment. Both are structurally and functionally related. 相似文献997.

The wrist joint is a complex joint containing several intrinsic and extrinsic ligaments that contribute to carpal stability. There is increased incidence of ligamentous/capsular injury following trauma.
Objective
The aim of this study was to assess the value of high resolution MDCT arthrography in detection of various ligamentous and capsular injuries of the wrist in post-traumatic writ pain.Patients and methods
From August 2016 to February 2017 Seventeen patients with posttraumatic wrist pain underwent MDCT arthrography primarily through radiocarpal injection and using high resolution study, all patients have negative MRI study of the wrist.Results
59% of cases had ligamentous/capsular tear. The most frequent was the capsular tears. Incomplete intrinsic ligament tears were observed, the dorsal scaphotrapezio-trapezoid ligament was the commonest to be affected. Class IA traumatic TFC tear was found in 12%. There was significant high positive correlation between the VAS score for wrist pain and the presence of ligamentous/capsular tear in absence of bone fracture.Conclusion
MDCT arthrography of the wrist is an excellent imaging method that can detect MRI occult ligamentous tear in unexplained post traumatic pain. 相似文献998.

While interpreting routine magnetic resonance imaging (MRI) of the knee joint, a radiologist may encounter various cystic lesions such as ganglion, synovial, and meniscal cysts, among others. In some cases, MRI may demonstrate cystlike lesions around the knee due to fluid distention of normal bursa and recesses, the diagnosis of which should not be difficult if a radiologist is familiar with their characteristic location and MRI appearance. In addition, there are cyst mimickers such as hematomas, abscesses, vascular lesions, and neoplasms around knee joint that may pose a diagnostic challenge on routine MRI. Due to their atypical location and variable morphology, contrast administration is helpful as the enhancement pattern aids to differentiate them from cysts and cystlike lesions. This pictorial essay aims to classify cysts, cystlike lesions, and cyst mimickers in and around the knee joint based on their anatomic location and highlight their characteristic MRI features. 相似文献
