Uses of surface/external phased array coils vs endorectal coil for the MR Imaging of the prostate gland

Uses of surface/external phased array coils vs endorectal coil for the MR Imaging of the prostate gland

Surface/external phased array coils (torso or cardiac) and/or endorectal coil (ERC) can be used for the multiparametric MR Imaging of the prostate gland. The ERC is a wire coil that is inserted through a small plastic tube into the rectum to obtain high quality images of the prostate gland and seminal vesicles. The coil consists …

High-resolution MR Imaging of the orbits and facial skull on a patient with squamous cell carcinoma

High-resolution MR Imaging of the orbits and facial skull on a moderately cooperative patient with squamous cell carcinoma (SCC) of the skin. SCC, the second most common form of skin cancer, is an uncontrolled growth of abnormal cells arising from the squamous cells in the epidermis, the skin’s outermost layer. SCCs may occur on all …

Important MRI Technique Used to Characterize Adrenal Lesions

Important MRI Technique Used to Characterize Adrenal Lesions

Left adrenal adenoma. Axial T1-weighted in- (A) and out-of-phase (B) images demonstrating signal drop-off on the out-of-phase sequence consistent with an adrenal adenoma with voxels containing both lipid and water protons. The most important MRI technique used to characterize adrenal lesions is CSI. In 1992, Mitchell and colleagues showed that CSI could detect intracellular lipid …

MR Imaging of the knee on a young patient with osteochondritis dissecans (OCD)

MR Imaging of the knee on a young patient with osteochondritis dissecans (OCD) OCD is the term first utilized in 1887 to describe the occurrence of a progeny osteochondral fragment separated from the parent bone. The etiology remains controversial considering genetic, traumatic, and vascular causes. In the knee, OCD most commonly occurs in the central …
