Objective

To detect the added value of magnetic resonance arthrography (MRA) over MRI in different triangular fibrocartilage complex (TFCC) and intrinsic wrist ligament lesions.

Patients and methods

MRI and MRA were achieved in 57 patients presented with wrist pain. Another symptompless Ten control individuals with negative MRI and MRA findings were included. Images were assessed for the presence of TFCC, scapholunate ligament (SCL) and lunotriquetral ligament (LTL) lesions. Imaging findings were compared with arthroscopic findings in all cases.

Results

Out of fifty-seven patients, 38 males (66.6%) and 19 females (33.3%) (age range 19–61 years (mean = 34.3 years) were included in the study, The sensitivity, specificity and accuracy of MRI and MRA for TFCC peripheral tears were 79.16%, 100%, 85.29% and 91.66%, 100%, and 94.11% respectively, the sensitivity, specificity and accuracy of MRI and MRA for TFCC central tears were 60%, 100%, 80% and 90%, 100%, and 95% respectively. Sensitivity, specificity and accuracy of MRI and MRA for SCL partial tears were 63.15%, 100%, 75.86% and 94.73%, 100% and 96.55%, respectively. For LTL partial tears, the values were 20%, 100%, 73.33% and 80%, 100%, and 93.33% respectively.

Adult thoracic and abdominal aortic coarctation, combined value of MSCTA and conventional angiography in endovascular management, Kaddaha, Randa O., Haggagb Magdy A., and Lotfyb Usama , The Egyptian Journal of Radiology and Nuclear Medicine, Volume 47, p.509–520, (2016) AbstractWebsite

Objective

To detect the value of MSCTA in diagnosis and preplanning in endovascular management of adult thoracic and abdominal coarctation. The additional value of conventional angiography before or during the procedures is explained. The follow-up by either techniques is evaluated for early detection of re-coarctation and re-intervention.

Patients and methods

This retrospective study included 22 patients, 9 females and 13 males, age ranging from 17 to 49 years. The main clinical presentation was hypertension (n = 15). All patients were evaluated by MSCTA and conventional angiography with pressure gradient studies for preoperative evaluation and planning of treatment. Follow-up MSCTA was done at 6 months interval for 3 years.

Results

MSCTA detected suprarenal MAS (n = 3), infrarenal and juxtarenal MAS (n = 10), pre- and post-coarctation dilatation of the thoracic aorta and subclavian (n = 4), thoracic collateral pathways (n = 5). Mean narrowest diameter is 2.3 mm (1.2–4.5 mm). In conventional angiography peak systolic gradient decreased from 33 to 2 mmHg. Successful endovascular repair was done in n = 15, PTA was done alone in 6 and PTA and stenting were done in n = 9. Endovascular re-intervention was done in n = 3.

Conclusion

Aortic COA could be found in any segment of the aorta. Proper identification of the anatomical details and pressure gradient studies are important factors affecting the plan of management.

MR Spectroscopy evaluation of white matter signal abnormalities of different non-neoplastic brain lesions, KADDAH, RANDA O., and Khalil Mohsen E. , The Egyptian Journal of Radiology and Nuclear Medicine, Volume 47, Issue 1, p.233–242, (2016) Abstract

Objectives

Our aim was to evaluate the efficacy of MR Spectroscopy in characterization of white matter signal abnormalities diagnosed by MRI detect changes in different metabolites and peaks of inflammation.

Patients and methods

93 patients (49 females and 44 males) age ranging from 2 to 63 years with average (37 ± 2.34 years) presented with white matter hyperintense lesions on T2 and T2 FLAIR and/or contrast enhanced T1WI diagnosed on MRI are included our study.

Results

In Infectious group: Average Cho/NAA ratio: 0.79 ± 0.19, Cho/Cr ratio: 0.95 ± 0.17, NAA/Cr 1.89 ± 0.69, in inflammatory group Cho/NAA ratio: 0.65 ± 0.15, Cho/Cr ratio: 0.98 ± 0.29, Average NAA/Cr ratio 1.69 ± 0.19. In ischemic group: Average Cho/NAA ratio: 0.83 ± 0.09, Cho/Cr ratio: 0.81 ± 0.23, Average NAA/Cr 1.54 ± 0.39, in metabolic group: Average Cho/NAA ratio: 0.57 ± 0.13, Cho/Cr ratio: 0.76 ± 0.26; NAA/Cr ratio was 1.73 ± 0.44, in mitochondrial group, Average Cho/NAA ratio: 0.62 ± 0.19, Cho/Cr ratio: 0.54 ± 0.14, NAA/Cr ratio was 1.49 ± 0.59, in inherited dysmyelinating; Cho/NAA ratio: 0.51 ± 0.17, Cho/Cr ratio: 0.63 ± 0.13; Average NAA/Cr ratio was 1.87 ± 0.65. Glutamate and myoinositol peak raised in inflammatory, infectious, metabolic, inherited, and ischemic group mainly in the acute and subacute stage. Amino acids and succinate peak specifically are raised in brain abscesses.

Conclusion

MRS is a noninvasive additional MRI technique to define the nature of non-neoplastic brain lesions. Together with image analysis, it may be the key to etiologic diagnosis or, at least, definition of the group where the lesion is classified, by detecting changes in different metabolites and peaks of inflammation.
