The limitations of functional MR imaging: a caveat.
The blood oxygen level dependent (BOLD) technique forms the technical basis for most functional magnetic resonance (fMR) imaging. The technique relies on the detection of elevated oxyhemoglobin levels draining an activated region of the brain. This recent development has great potential for further understanding cognitive behavior, monitoring pharmacologic actions, and, in particular, for preop...
متن کاملThyroid Nodule Imaging. Status and Limitations.
Thyroid nodules are common, occurring in almost two-thirds of some populations; among these only about 7% are malignant. The most important question with any new discovered thyroid nodule is, “is this malignant?” The main arbiter of malignancy or benignity remains fine needle aspiration and the mainstay of treatment surgery.

متن کاملMR imaging
Biliary tract neoplasms are commonly accounted for by cholangiocarcinoma and biliary cystadenoma/carcinoma and other less common tumors including papillary neoplasms, lymphoma and metastases. Although cholangiocarcinoma is a rare tumour (<2% of all cancer), it is the second most common primary hepatobiliary malignant tumour after hepatocellular carcinoma (HCC). This tumour actually encompasses ...
متن کاملMR imaging of neurocysticercosis.
Twenty-six patients with neurocysticercosis were studied with MR imaging to correlate their clinical presentation with the location and appearance of their neurocysticercosis lesions. Intraventricular cysts were present in 14 patients (54%), parenchymal cysts were present in 18 (69%), and intraventricular together with parenchymal cysts were present in six (23%). Intraventricular cysts were det...
