Study confirms link between angio contrast and long-term kidney damage
The use of x-ray contrast media in patients with kidney impairment can result in higher rates of long-term adverse events such as death, heart attack, and stroke, and different contrast agents can have varying adverse event rates, according to a study published online today in the Clinical Journal of the American Society of Nephrology.

Moly crisis overshadows SNM Image of the Year award
TORONTO - Dr. Henry Wagner's Image of the Year award is always a highlight of the annual SNM conference, but Monday was probably the first time he's given the presentation to a packed press room and a bank of TV cameras due to the ongoing molybdenum-99 crisis.

DIAD follow-up confirms SPECT MPI guidelines for diabetic patients
TORONTO - Asymptomatic patients with type 2 diabetes who have abnormal electrocardiogram (ECG) results should receive myocardial perfusion SPECT workup due to their worse prognosis compared to those with normal ECGs, according to follow-up research to the Detection of Ischemia in Asymptomatic Diabetics (DIAD) study that was presented Sunday at the SNM meeting.

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.
