CT perfusion distinguishes HCC from other liver lesions

Radiologists in China are getting more traction out of their CT liver protocols with the use of perfusion dual-source CT (DSCT) exams, taking a bite out of MRI's traditional superiority in the process. DSCT is showing that it can often do a better job in differentially diagnosing hepatocellular carcinoma (HCC), liver metastases, and cavernous hemangioma in the clinical setting.

CT calcium scores boost value of cardiac risk factors

A new analysis of a major cardiac risk study published today in the Journal of the American Medical Association found that CT coronary artery calcium scoring significantly boosts the power of traditional risk factors for predicting adverse cardiac events over the long term.

Coronary CTA best next test for positive stress patients

Asymptomatic individuals with positive cardiac stress results should proceed to coronary CT angiography (CTA) rather than an invasive cardiac catheterization, according to a new report in the May American Journal of Roentgenology. The study found that low-risk patients received more cost-effective care by using coronary CTA as a gatekeeper test.

CT attenuation improves sensitivity for bowel wall obstruction

A technique that analyzes the attenuation of small regions of interest in the bowel wall at CT can improve the diagnosis of suspected bowel wall ischemia, a condition associated with substantial morbidity and mortality, according to a study in the April American Journal of Roentgenology.

Small colon polyps on VC suggest presence of larger lesions

Individuals with several diminutive colon polyps on virtual colonoscopy studies are far more likely than other screening subjects to also have a larger colorectal lesion, say researchers from the University of Munich in Germany.

Automated exposure control delivers uneven CT dose reduction

Reducing tube current may be a popular way to lower CT radiation dose, but it's not necessarily an effective one. In a new study, medical physicists from Greece found that organ dose reductions resulting from tube current modulation with automated exposure control can vary -- especially in children.

CT shows abdominal fat is unreliable Crohn's treatment target

A few reports have associated abdominal visceral fat with more aggressive forms of Crohn's disease, but the strength of the association -- and the implications for treatment -- remain unclear. Researchers from Ireland decided to try CT to resolve the issue.

Less DNA damage seen after high-pitch coronary CTA

High-pitch dual-source CT angiography (CTA) scans produce significantly less radiation-related DNA damage than comparable low-pitch dual-source CTA scans -- and, importantly, the DNA results correspond to both measured and derived biological radiation doses, say researchers from Erlangen, Germany.

Carotid ultrasound may help predict cardiac events

Performing ultrasound studies of carotid intima-media thickness provides long-term prognostic value for adverse cardiac events, giving doctors important clues about who is at risk for a heart attack, according to a study published April 6 in the Journal of the American College of Cardiology.

Elastography tracks stiffness changes in breast implants

By Amerigo Allegretto

Shear-wave elastography could be used as an indicator of breast implant rupture risk.

(A) Examples of B-mode images for the measurement of membrane thickness of implants from each of the four types of implants. Images are presented at the same scale. Membrane thicknesses (B) and then shear moduli measured by ARFI method (C) are compared without dissociation as a function of prosthesis age or implantation time. (NS: p-value > 0.05, *: p-value < 0.05, **: p-value < 0.01, ***: p-value < 0.001).

PET/CT scans show value in patients with rare type of pancreatitis

F-18 FDG-PET/CT scans may help predict relapses in patients with autoimmune pancreatitis.

January 19, 2024

F-18 FDG-PET/CT images of patients. (A) Image of a 61-year-old male patient with type 1 autoimmune pancreatitis (AIP) demonstrating diffuse enlargement of the pancreas (arrows). The serum IgG4 level was 2,260.0 mg/dL, and the TLG2.5 was 413.8 g/ml×cm3. According to the nomogram, his relapse probability is more than 95%. The patient discontinued steroid use during the maintenance phase, and 7 months later, he relapsed, with imaging showing diffuse re-enlargement of the pancreas. (B) Image of a 60-year-old male patient with type 1 AIP, showing focal enlargement in the head of the pancreas (arrows). The serum IgG4 level was 980 mg/dL, and the TLG2.5 was 92.7.0 g/ml×cm3. According to the nomogram, the patient’s relapse probability is less than 50%. After symptom relief, the patient did not receive maintenance treatment, and has been followed up for 4 years without relapse. Image courtesy of BMC Gastroenterology.
