Structural MR Imaging

MR 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 ...

Subacute sclerosing panencephalitis findings at MR imaging, diffusion MR imaging, and proton MR spectroscopy.

A case of subacute sclerosing panencephalitis in a 2-year-old boy is reported. In addition to asymmetric lesions in the parietotemporal lobes, right thalamus, and globus pallidus, symmetric patterns were notable in the brain stem, middle cerebellar pedincles, and dentate nuclei. Proton MR spectroscopy revealed markedly decreased N-acetylaspartate peaks and normal choline and myo-inositol levels...

MR 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...

Integrin Targeted MR Imaging

Magnetic resonance imaging (MRI) is a powerful medical diagnostic imaging modality for integrin targeted imaging, which uses the magnetic resonance of tissue water protons to display tissue anatomic structures with high spatial resolution. Contrast agents are often used in MRI to highlight specific regions of the body and make them easier to visualize. There are four main classes of MRI contras...
