Australian center halves CCTA dose using simple techniques

An academic heart center in Australia has cut its coronary CT angiography (CCTA) dose in half over three years using simple techniques that emphasize prospective triggering, low kV settings, and aggressive beta-blockage, according to research presented at the Society of Cardiovascular Computed Tomography meeting in Baltimore.

ROMICAT II: CCTA more efficient to triage chest pain patients

It's more efficient to use coronary CT angiography (CCTA) to rule out coronary artery disease for chest pain patients, according to results of the long-awaited Rule Out Myocardial Ischemia/Infarction Using Computer Assisted Tomography (ROMICAT) II trial, published on Wednesday in the New England Journal of Medicine.

SCCT: Dual-energy CTA may offer more accurate look at plaque

A new dual-energy CT angiography (DECTA) protocol may provide a more accurate look at coronary artery calcium by eliminating artifacts that can bedevil more conventional CTA approaches, according to researchers from Virginia at this week's Society of Cardiovascular Computed Tomography (SCCT) meeting in Baltimore.

ACC-based software boosts appropriateness of heart scans

American College of Radiology guidelines aren't the only ones being used to develop software to rein in inappropriate utilization. A new decision-support tool based on American College of Cardiology (ACC) appropriateness criteria demonstrated its value in reducing unnecessary cardiac imaging exams in a recently completed pilot project.

Chronic kidney failure no barrier to CT angiography

CT angiography using moderate doses of IV contrast in patients with advanced renal failure is a safe procedure that negatively affects renal function in only a small percentage of patients, according to researchers from Baltimore.

CT nanoparticle contrast: Good as gold?

CT nanoparticle-based contrast agents are all investigational -- and at this point all preclinical -- but they're out there. In a few years, the tiny contrast agent delivery vehicles, which work well in animals, could greatly affect the diagnosis and treatment of disease in humans.

New spectral imaging options improve abdominal CTA

CT angiography (CTA) of the abdomen is a well-established method for answering any number of diagnostic questions, but in the past couple of years it's gotten even better. Recent technical advances, such as spectral imaging CT at different energy levels, can improve the modality's diagnostic power, reducing dose and contrast use.

BMJ: Twice is the key to cost-effective AAA screening

Danish researchers have found a sort of Goldilocks solution to the question of whether abdominal aortic aneurysm (AAA) screening is cost-effective if performed repeatedly rather than just once in a patient's lifetime. The most cost-effective scenario is twice, they reported on Friday in the British Medical Journal.

PE studies highlight risks, benefits of CT exams

A series of studies and an expert panel discussion published in the American Journal of Roentgenology highlight the benefits and risks of CT exams for detecting suspected pulmonary embolism (PE). On the whole, they downplayed the notion that the modality is overused.

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

Using AI with mammography can help select women for breast MRI

By Amerigo Allegretto

Using AI with mammography can help select women at high risk of breast cancer for supplemental MRI.

February 4, 2025

Images depict a 55-year-old woman with a family history of breast cancer who underwent combined mammography and MRI screening. (A) Right and (B) left mediolateral oblique and (C) right and (D) left craniocaudal mammograms show a large known cyst in the left breast (arrow in B and D), but were otherwise assessed as being unremarkable. Breast tissue was judged to be extremely dense. (E) Concurrent axial subtraction MRI scan shows a large, diffuse, invasive lobular cancer (circle) in the right breast. The AI system provided a case-based cancer suspicion score of 8 on a scale of 0-10, which would have led to selection for MRI screening using both the score 5 and score 8 thresholds, but not the score 9 threshold.
