SIR: Venous angioplasty relieves multiple sclerosis symptoms

SAN FRANCISCO - A controversial theory that vascular blockages cause multiple sclerosis (MS) found additional support this week at the Society of Interventional Radiology (SIR) meeting. Researchers showed that using vascular angioplasty to clear blocked veins also quelled some MS symptoms.

MRI uncovers cardiovascular risks for 9/11 first responders

Exposure to dust produced from the collapse of the twin towers at the World Trade Center on September 11, 2001, is subjecting the first responders to that disaster to an elevated risk of cardiovascular disease, according to results of a study involving dynamic contrast-enhanced MRI.

CT lung screening gets boost by adding COPD sequence

Low-dose CT lung screening has already demonstrated its effectiveness in reducing mortality from lung cancer. Now, Dutch researchers have found that adding a short sequence to the low-dose CT protocol can help the modality detect chronic obstructive pulmonary disease (COPD), according to a study published on Tuesday in the Journal of the American Medical Association.

PCCT has higher safety profile than EID-CT for lung imaging

By Amerigo Allegretto

Photon-counting CT (PCCT) leads to fewer adverse outcomes than energy-integrating detector CT (EID-CT), researchers say.

Subgroup analysis based on lesion size on PCCT images. The red outlined areas highlight the magnified images of lesions. (A-C) PCCT images in a 62-year-old woman with a body mass index (BMI) of 23.6, calculated as weight in kilograms divided by height in meters squared, who was diagnosed with adenocarcinoma. A lesion with a long diameter of 25 mm was identified in the right lower lobe on axial images acquired during the venous phase. For lesions less than or equal to 30 mm, decreasing section thickness improved boundary sharpness and contrast between the necrotic area and enhanced tissue, with optimal visualization at 0.4 mm. (D-F) PCCT images in a 66-year-old man with a BMI of 24.2 who was diagnosed with adenocarcinoma, revealing a lesion with a long diameter of 52 mm in the right lower lobe. For lesions greater than 30 mm, a section thickness of 1 mm demonstrated better contrast and clarity at the boundary of the necrotic area compared with 0.4 mm. This observation supported the selection of an appropriate section thickness for accurate quantification of necrotic regions within the lesion.
