H7N9 bird flu pneumonia scans show common imaging findings

A new bird flu strain known as influenza H7N9 appeared in China this year and quickly took a number of human victims. An article in Radiology published on Tuesday includes some of the first radiologic images of the effects of the virus, revealing typical patterns of progression and regression on CT scans and radiographs of the chest.

BMJ: CT detects pulmonary emboli that should stay lost

Clinically insignificant pulmonary emboli are overdiagnosed by CT and overtreated with anticoagulants, concludes an editorial published in BMJ. Today's CT scanners do a great job of finding the smallest clots, but patients are at risk of unnecessary treatment.

Wide-area 640-slice coronary CT angiography cuts contrast dose

Chinese researchers performing coronary CT angiography on a wide-area CT scanner with 640-slice reconstruction found they could substantially reduce the use of contrast media -- at least in nonobese patients with well-controlled heart rates.

CT perfusion salvages nondiagnostic CTA for stent assessment

Combining CT perfusion scans with CT angiography (CTA) can improve the diagnosis of coronary artery disease in stent patients, visualizing stenotic vessel segments that CTA alone is hard-pressed to characterize, German researchers reported today in the Journal of the American College of Cardiology.

Women can start colon cancer screening later than men

Women can be screened for colorectal cancer five to 10 years later than men, according to an Italian study published on June 11 in Cancer. The different findings for men and women in more than 7,000 patients could eventually translate into different screening recommendations based on gender, the investigators wrote.

BMJ: Megastudy links pediatric CT to higher cancer rates

The largest study to probe the effects of ionizing radiation since the atomic bomb survivor studies shows that cancer incidence does rise among younger patients -- although only in small amounts -- in the years following their exposure to CT scans, according to an Australian article published yesterday in BMJ.

Postmortem MRI shows sudden cardiac death invisible at autopsy

In results that add substantial forensic power to identifying the cause of death, postmortem cardiac 3-tesla MRI has been found to identify sudden cardiac death in cases that are invisible at conventional autopsy, according to new research published online in the Journal of the American College of Cardiology.

Unfilled vacancies and disparities persist in nuclear medicine

Nuclear medicine specialists have high career satisfaction, but unfilled vacancies and career disparities persist, finds a workforce survey by the European Association of Nuclear Medicine (EANM).

Dual PET imaging in Case Two illustrates a patient with discordant disease. FDG PET (b & d) shows FDG uptake in tail of pancreas primary lesion (yellow arrow), as well as multiple hepatic metastases (yellow boxes), with enlarged liver span. DOTATATE PET on left (a) shows several hepatic metastases that do not demonstrate DOTATATE uptake above background of liver parenchyma. The liver lesions in (c) demonstrate moderate FDG uptake in liver lesions, with no corresponding DOTATATE avidity (white box) or central photopenia (white arrow). This discordance in dual PET imaging corresponds to a NETPET score of 5. This suggests de-differentiated disease and a less favorable prognosis. The patient was not suitable for Lutate treatment and received chemotherapy.
