JAMA: CCTA generates more interventions versus stress testing
An analysis of more than 300,000 Medicare patients being evaluated for heart disease found that those who received coronary CT angiography (CCTA) were more likely to go on to invasive cardiac procedures compared with those who received myocardial perfusion scintigraphy, according to results published in the November 16 Journal of the American Medical Association.

Pediatric MRI not always safer than CT
CT versus MRI -- the latter is the obvious choice for children because MRI does not use ionizing radiation, right? Actually, CT can be safer depending on the exam, say researchers eyeing the comparative risks of the modalities.

Pericolonic fat associated with adenomatous polyps
Friday, December 2 | 10:30 a.m.-10:40 a.m. | SST04-01 | Room E350Patients with adenomatous colorectal polyps have higher fat volume fractions than patients without these polyps, according to a multipurpose virtual colonoscopy scan. The pairing sounds obvious enough, but researchers from Bethesda, MD, believe the results suggest that pericolonic fat itself may be the culprit behind adenoma growth.

Heavy-metal contrast cuts radiation dose
Wednesday, November 30 | 3:10 p.m.-3:20 p.m. | SSM20-02 | Room S404ABCompared with some heavy metals, iodine and barium simply don't produce enough contrast in CT to optimize dose, according to medical physicist Tristan Nowak, from the Institute of Medical Physics at Friedrich-Alexander-University Erlangen-Nuremberg. In a study to be presented Wednesday afternoon, his group tested several heavy metals in phantoms in the search for an eventual replacement.

2-hour prep may ease VC scheduling after optical colonoscopy
Tuesday, November 29 | 3:40 p.m.-3:50 p.m. | SSJ08-05 | Room E450BWhen a conventional colonoscopy fails to reach the cecum, virtual colonoscopy is a logical choice to complete the screening. But it can be difficult to refer these patients to VC fast enough to avoid a second bowel cleaning. Fortunately, a two-hour prep might be effective enough to spare the patient an extra trip to the clinic, according to a study being presented in a Tuesday session on VC techniques.

CT perfusion quantifies neoangiogenesis in HCC tumors
Tuesday, November 29 | 11:10 a.m.-11:20 a.m. | SSG05-05 | Room E353CResearchers in Italy believe that CT perfusion can noninvasively quantify tumor blood supply in hepatocellular carcinoma (HCC) that relates to tumor neoangiogenesis, a process that is essential for tumor growth. The knowledge will help doctors better assess the disease and strategize treatment options, they said.

Myocardial perfusion stress CT moves to clinical use
Tuesday, November 29 | 10:50 a.m.-11:00 a.m. | SSG02-03 | Room S503ABCardiac CT is ready for the comprehensive assessment of coronary artery disease in routine clinical use, say researchers from the Medical University of South Carolina. In the group's initial experience applying myocardial perfusion CT to a clinical population with acute chest pain, the technique detected myocardial perfusion defects just as well as the reference standards, MRI and SPECT.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

Highly processed foods affect muscle quality
By Will Morton
MRI scans have revealed that eating ultraprocessed foods is associated with higher amounts of fat stored inside thigh muscles.
December 4, 2024
Axial T1-weighted bilateral thigh MR images and magnified frames providing a closer look at the areas in lateral aspects of quadriceps femoris muscles (knee extensors) from two obese, female participants, aged 58 (A) and 62 years (B), respectively. In A, the thigh muscles on both sides demonstrate abundant fatty streaks, consistent with a high Goutallier grade for this participant, whose diet from the past 12 months consisted of 68% ultraprocessed foods. In B, the thigh muscles show fewer fatty streaks as highlighted in the magnified image, consistent with a low Goutallier grade for this participant, whose diet contained only 36% ultraprocessed foods.
