abstract patellar instability is a multifactorial common knee pathology that has a high recurrence rate, and the symptoms continue and ultimately predispose the patient to chondromalacia and osteoarthritis. tibial tuberosity-trochlear groove distance (tttg) is very important in the assessment of patellofemoral joint instability. the purpose of this study was to report normal value of tttg in ma...

introduction a discoid medial meniscus is a rare pathology of the knee joint, and is even rarer when it presents bilaterally with clinical symptoms. case presentation we present the case of a 38-year-old female with symptomatic bilateral discoid medial meniscus. magnetic resonance imaging (mri) showed complete discoid meniscus in one knee and incomplete, on the other side. the mri findings were...

conclusion in breast cancer after nac, the lesion t2 relaxation time was reduced in the responders, and this finding is potentially useful to assess the response to nac. results in 26 cases with nac, the mean lesion t2 relaxation time before nac was 81.34 ± 13.68 ms, compared with 64.50 ± 8.71 ms after nac. significant differences in the lesion t2 relaxation times existed between the pre- and p...

New research from Case Western Reserve University (Cleveland, OH) shows that magnetic resonance imaging (MRI) can detect the earliest signs of breast cancer recurrence and fast-growing tumours. The new MRI technique detects micrometastases, breakaway tumour cells with the potential to develop into dangerous secondary breast cancer tumours elsewhere in the body, according to the study published ...

Two women with breast carcinoma developed clinical evidence of a sphenocavernous syndrome with magnetic resonance (MRI) that suggested a basal skull meningioma but in whom biopsy of the lesion revealed metastatic breast carcinoma. The difficulties in distinguishing between the two lesions on the basis of standard MRI are discussed, as are newer imaging techniques that may reduce or eliminate th...

background studies show that a large proportion of healthcare offered may be inappropriate or unnecessary. magnetic resonance imaging (mri) is a new and expensive diagnostic technology which has been increasingly used all over the world. moreover, this trend has been more rapidly increasing in iran. low back pain is a common disorder all over the world and mri technique is one of the several wa...

results stereoscopic displays of the nerves were obtained in all 24 elbows by vr, mip, and fiber tractography post-processing methods. the vr/mip post-processing methods were easier to perform compared to fiber tractography. there was no significant difference among the scores of fiber tracking and vr/mip reconstruction for single direction. the imaging quality scores of fiber tractography and ...

conclusions ti is an important parameter to consider in the relationship between si and nanoparticle concentrations. an increase in ti leads to a decrease in the range of linearity. results the results indicate that si depended on the concentration of nanoparticles and ti. in addition, si increased by increasing the tis ranging from 200 to 400 ms for all studied concentrations. the linear relat...
