Gadobutrol-enhanced MRI of the liver on a patient with hepatic hemangioma Hemangiomas are common focal liver lesions, usually detected in the work up of asymptomatic patients. MRI is the imaging method of choice to diagnose hemangiomas. On T1-w images, hemangiomas display low signal intensity and on T2-w, they are strikingly homogeneous, clearly demarcated from the …

Pituitary macroadenomas are the most common suprasellar mass in adults, and responsible for the majority of transsphenoidal hypophysectomies. They are defined as pituitary adenomas greater than 10 mm in size and are approximately twice as common as pituitary microadenomas. MRI is the preferred imaging modality, not only able to delineate the mass exquisitely but also …

A normal proton brain spectrum is seen in this figure. Notice that the zero frequency is on the right-hand side of the spectrum and it is usual to read the spectrum from right to left. The metabolites have a unique pattern of peaks at specific chemical shifts and the presence and concentration of these chemicals …

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 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 …
