Direct evidence that the VEGF-specific antibody bevacizumab has antivascular effects in human rectal cancer
It is shown that a single infusion of the VEGF-specific antibody bevacizumab decreases tumor perfusion, vascular volume, microvascular density, interstitial fluid pressure and the number of viable, circulating endothelial and progenitor cells, and increases the fraction of vessels with pericyte coverage in rectal carcinoma patients.

Autoimmune pancreatitis: imaging features.
Features that suggest autoimmune pancreatitis include focal or diffuse pancreatic enlargement, with minimal peripancreatic inflammation and absence of vascular encasement or calcification at CT and endoscopic US, and diffuse irregular narrowing of main pancreatic duct, with associated multiple biliary strictures at ERCP. Expand
Venous compression syndromes: clinical features, imaging findings and management.
Venous compression syndromes, including Paget-Schroetter syndrome, Nutcracker syndrome, May-Thurner syndrome and popliteal venous compression will be discussed. Expand
MR imaging of the gallbladder: a pictorial essay.
The gallbladder serves as the repository for bile produced in the liver. However, bile within the gallbladder may become supersaturated with cholesterol, leading to crystal precipitation andExpand
Assessing tumor perfusion and treatment response in rectal cancer with multisection CT: initial observations.
Perfusion CT of rectal cancer can enable assessment of tumor vascularity and perfusion changes that result from chemotherapy and radiation therapy and, in this small patient sample, tumors with initial high BF and short MTT values tended to respond poorly to chemotherapy and Radiation therapy.

Quality Improvement Guidelines for Transjugular Intrahepatic Portosystemic Shunts.
This work presents a meta-analyses of the prophylactic and non-prolific use of positron emission tomography for the diagnosis and treatment of central giant cell granuloma in eight patients with central nervous system injuries. Expand
Natural history and CT appearances of aortic intramural hematoma.
On the basis of CT findings, some hematomas may be expected to resolve spontaneously, whereas others may be identified as posing a high risk for serious complications such as aortic dissection, aneurysm, and rupture. Expand
Segmental arterial mediolysis: clinical and imaging features at presentation and during follow-up.
SAM affects middle-aged and elderly patients andVisceral artery dissections and aneurysms are common and the disease progresses in nearly half the patients, and Serial follow-up with computed tomographic angiography and/or magnetic resonanceAngiography may be necessary to monitor disease progression.
