Background
Assessment of treatment response in patients with a brain tumor is paramount, as true tumor recurrence and radiation necrosis are similar looking on conventional MRI.Purpose
To evaluate the role of dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging in the differentiation between recurrent brain tumors and radiation necrosis.Material and Methods
Twenty patients with a history of operated primary brain tumors and postoperative radiotherapy with or without chemotherapy were enrolled in this prospective study having conventional MRI findings of enhancing lesion suspicious of being recurrence or radiation necrosis. All patients were examined by DSC-perfusion MRI. Definitive diagnosis was reached through either subsequent surgical biopsy or follow up over 6-12 months.Results
Fifteen patients (75%) were diagnosed as tumor recurrence and 5 patients as radiation necrosis (25%). The relative cerebral blood volume (rCBV) and relative peak height (rPH) were significantly higher (P?<?0.05) in recurrent tumors than in radiation necrosis lesions. The rCBV and rPH thresholds in differentiating between them were 1.8 and 1.22 respectively with 87%, 93% sensitivity and 100% specificity for each respectively.Conclusions
DSC-perfusion MRI is a valuable non-invasive tool besides conventional MRI whenever available to differentiate between radiation injury changes and tumor recurrence. 相似文献3.

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5.

Purpose
To evaluate the diagnostic power of MRI criteria in, the detection of the placental topography and depth of invasion in, morbidly adherent placenta.Patients and methods
This study included forty pregnant patients, referred to MRI unit with suspected placental invasion by ultrasound. MRI, was done using fast sequences (B-FFE and SSH TSE). Placental topography, architecture and depth of invasion were analysed. MRI criteria suggestive, of invasion were evaluated (loss of retroplacental zone, thick dark, intraplacental bands and disorganized vascularity). The gold standard was, the surgical findings. This study determined the most sensitive, specific, and accurate MRI criteria as well as the degree of agreement with, operative findings.Results
MRI detected placental invasion in 16 cases out of 40. Operative, findings confirmed 12 of them. MRI achieved100% sensitivity, 85.7%, specificity and 90% accuracy. The MRI criterion of highest, sensitivity, specificity and accuracy was loss of retroplacental zone, (100%, 92.8% and 95% respectively). Good agreement between MRI and the, operative data was encountered (kappa value 0.78).Conclusion
MRI criteria are accurate markers for the detection and, staging of placental adhesion, which guide the obstetrician to achieve, the optimum surgical management. 相似文献10.

Purpose
To evaluate the role of MRI of the brain in women with postpartum convulsions and correlate them with clinical data.Patients and Methods
In a prospective study, a total of 96 patients with postpartum convulsions were delivered between January 2012 and March 2016. All patients were referred from Ob-Gyn department to radiology department for MRI evaluation of the brain. They were included after meeting the inclusion criteria which depends on the clinical data. MRI findings were collected and classified according to final diagnosis.Results
MRI examination of the brain was positive in 56 patients (56.2%) out of 96 patients who presented with postpartum convulsions. Dural sinus thrombosis was the commonest finding; it was detected in 19 patients. Posterior reversible encephalopathy was encountered in 18 patients. Intra cerebral hemorrhage and subarachnoid hemorrhage were encountered in 10 and 6 patients respectively. Only one patient had pituitary apoplexy, one had carotid aneurysm and one had glioma. The remaining 40 patients had negative MRI.Conclusion
Post partum convulsion is a serious condition and may be caused by delayed eclampsia or other pathological condition. MRI can help solving this problem if clinical data was unreliable. 相似文献14.

Objectives
To create a systematic approach using computed tomography (CT) and magnetic resonance imaging (MRI) findings to facilitate identifying the etiology of hearing loss, evaluating the anatomy for surgery, and predicting complications.Methods
Twenty nine pediatric patients with congenital or acquired sensory-neural hearing loss (SNHL) requiring cochlear implant (CI) were included. They underwent combined CT, 3D DRIVE MRI axial plane and axial T2WIs for the whole brain. The inner ear, cochlear nerve development, temporal bone anatomy, operative window, normal variants and causes of central hearing loss were assessed.Results
CT showed that 100% of the patients are suitable for CI while MRI showed that 96.5% of studied patients are suitable. The examined ears were categorized into 4 groups according the candidacy for operation; 86.2% were suitable for CI, 5.1% were suitable for CI but with expected poor response, 1.7% of examined ears were suitable for CI with modification of surgical procedure and 6.8% were not suitable for CI.Conclusion
In Suez Canal area, the combined CT/MRI approach categorized the majority of patients with SNHL (96.6%) as good candidates for CI. 相似文献19.
