SIGGAR study finds preference for VC, but dislike of more tests

Patients undergoing virtual colonoscopy experience less pain and discomfort and more overall satisfaction than those undergoing conventional colonoscopy, a recent research study has found. Months after the exam, however, perceptions of the experience evened out.

Additional CT recommended when FNA is negative

Fine-needle aspiration (FNA) appears to be the best way to diagnose lung cancer when low-dose CT finds suspicious lesions, but it can produce false negatives, according to a new study in the Journal of Thoracic Oncology.

Routine CT lung cancer screening a low-cost lifesaver

Routine CT lung cancer screening of high-risk individuals would save thousands of lives per year for less than a dollar a month per patient if it were implemented throughout the U.S. -- and would be even cheaper than breast screening, concludes a new study in the April issue of Health Affairs.

MESA: Metabolic syndrome, diabetes boost CAC, cardiac events

People with metabolic syndrome and/or diabetes mellitus have greater progression of coronary artery calcium (CAC) than those without the conditions, and the degree of progression in CAC predicts the risk of future cardiac events, according to a study in the Journal of the American College of Cardiology.

'Fatter' phantoms expose radiation's burden on the obese

It is well known that medical radiation dose is greatly affected by patient size, but less well known is the impact of other factors like fat composition. Authors of a new study in Physics in Medicine and Biology got a better handle on dose by creating phantoms that approximate the body habitus of overweight patients.

MDCT generates few new cancers among Medicare patients

Medicare-aged adults get more multidetector-row CT (MDCT) scans than anyone else, but it doesn't seem likely that the scans will kill them, according to a study on the risks of radiation dose in the April issue of the Journal of the American College of Radiology.

Digestive disorders lead to high radiation doses over time

Patients with gastrointestinal disorders may be exposed to significant doses of radiation from abdominal CT over time, concludes a new study in Clinical Gastroenterology and Hepatology. Researchers found higher levels of annual and total diagnostic radiation exposure in these patients.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Could AI scoring help with managing DCIS?

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.

Clinicians, beware: CT diagnostic accuracy varies by adnexal lesion type

Ultrasound ablation is effective for treating hyperparathyroidism

By Amerigo Allegretto

Ultrasound-guided thermal ablation techniques are safe and effective in treating patients with secondary hyperparathyroidism.

January 7, 2025

Ultrasound images depict a 63-year-old man who underwent radiofrequency ablation (RFA) for the treatment of secondary hyperparathyroidism. (A–D) 2D images show four hyperplastic parathyroid glands on the right and left sides (marked with crosshairs). The numbers near the crosshairs represent the number of measured trails. (E) Ultrasound-guided infusion of isolation fluid (arrowheads) around the hyperplastic parathyroid gland to protect vital organs such as the trachea (Tr), carotid arteries (CA), and recurrent laryngeal nerve pathway area (arrow). F) Ultrasound-guided RFA of the hyperplastic parathyroid gland. (G) Immediate postoperative contrast-enhanced ultrasound shows no contrast enhancement in the ablation area. The ablation procedures for the other three parathyroid glands were the same as those described above. Image courtesy of the RSNA,
