Stage 1 or 2 AVN without subchondral collapse or secondary osteoarthritis often presents in young patients with age range of24-45 years. It is often idiopathic or corticosteroid-induced.42For this population, core decompression, osteotomy in consideration for bone grafting, and vascularized fibular ...
SpineWe performed Gd-DTPA enhanced MRI in two patients with ankylosing spondylitis (AS), and noticed interesting long T1 and T2 lesions and enhancement in the cephalad and caudal portions of the vertebral bodies in one case, particularly prominent in the ventral and dorsolateral aspects. These ...

When a previous back surgery has been performed, MRI scans with and without contrast can help differentiatescar tissuefrom a hematoma or recurrent disc herniation. Prior to administering anepidural steroid injection, if a tumor or infection is suspected, an MRI scan can help determine if the injec...
Both parallel imaging and flip angle modulation, however, have associated tradeoffs; a signal penalty with the former and diminished image contrast with the latter. Coils A combination of integrated in-table and surface coils is used for WB-MRI. Surface coils are multichannel multielement receiver ...
MRA scans can be performed with a contrast material or without. If required, the technologist administers the contrast material in a vein of your arm through a small intravenous (IV) catheter. The technologist may or may not inject a contrast dye into your forearm or hand to help improve th...
MRI provides good contrast resolution of bone and soft tissue and therefore has good sensitivity and specificity for the detection for bone metastases [7,9,13]. However, limited field of view and long examination time pose problems, which existed even before the development of WB-MRI. ...
