DECT cuts tests as a one-stop myocardial, coronary artery exam

A single dual-energy CT (DECT) exam can provide an accurate, integrative analysis of coronary artery morphology and myocardial blood supply, according to researchers from the Medical University of South Carolina. The study highlights the potential of DECT as a one-stop shop.

Dual-source coronary CTA has advantages over 64-slice

Even in patients with well-controlled heart rates, dual-source coronary CT angiography (CTA) delivers significantly higher specificity and accuracy per coronary segment compared to 64-detector-row CTA, concludes a new study from Switzerland.

Lower-kilovoltage coronary CTA maintains image quality

In a study that included all but the heaviest cardiac imaging patients, European and Japanese researchers were able to cut radiation dose by 31% in coronary CT angiography (CTA) studies by reducing the kilovoltage from 120 kV to 100 kV, with no difference in image quality.

Sophisticated electronic bowel cleansing boosts polyp detection

A new suite of investigational image-processing tools known as structure-analysis cleansing is improving the results of virtual colonoscopy scans performed after limited bowel preparation. The goal is to make virtual colonoscopy easier on patients and persuade them to get screened for colorectal cancer.

Zero calcium means good outcomes, even with undetected plaques

Patients with coronary artery plaques -- soft, mixed, or otherwise -- that go undetected in a calcium scan still have a good prognosis, according to a new study presented at last week's Society of Cardiovascular Computed Tomography meeting in Orlando, FL.

PET/MRI may help diagnose fevers of unknown origin

PET/MRI imaging shows promise in diagnosing fevers or inflammation of unknown origin and may have advantages over PET/CT.

In an example image from the study, F-18 FDG-PET/MRI fusion image (A) and PET 3D image (D) show a moderately increased FDG uptake in muscles around hip joints. T2 IDEAL WATER image (B) shows increased T2 signal; LAVA WATER (C) image shows mild enhancement in these muscles. Findings were suspicious of myositis, which was histopathologically confirmed.

PET reveals patterns underlying cognitive decline in patients with DLB

F-18 FDG-PET imaging in patients with dementia with Lewy bodies (DLB) has shown that brain hypo- and hypermetabolism may have different affects on cognition.

January 5, 2024

DLB-hypo (hypometabolic changes in dementia with Lewy bodies) was characterized by relatively reduced bilateral metabolic activity (color-coded blue) in the bilateral parietal, temporal, and occipital cortices, while DLB-hyper (hypermetabolic changes in dementia with Lewy bodies) showed relatively increased metabolic activity (color-coded red) in the cerebellum, bilateral sensorimotor, orbitofrontal, insular, and parahippocampal cortices, bilateral putamen, globus pallidum, hippocampus, and amygdala.

MRI helps clinicians assess neural involvement in endometriosis

MRI could help clinicians assess neural involvement in endometriosis and help prevent irreversible nerve damage and chronic sensorimotor neuropathy.

Spectrum of imaging features of nerves involved in endometriosis in three women. (A) Coronal T1W contrast-enhanced MR image in a 44-year-old woman shows a thickened left sciatic nerve with increased enhancement (solid arrows) and a fibrotic mass (*). The right-side sciatic nerve is normal in appearance (dashed arrows). (B-D) Axial T1W image (without contrast enhancement) with fat saturation (B) in a 43-year-old woman shows a cystic endometriotic lesion with signal hyperintensity (arrow in B). The adjacent left iliacus muscle is asymmetrically thickened due to involvement by endometriosis (* in B). Axial T2-weighted MR image (C) at the same level as B shows T2 shading in the cystic lesion (arrow in C) and a fibrotic mass replacing the iliacus muscle (* in C). Sagittal T2-weighted MR image (D) shows the sacral nerve roots (dashed arrows in D) encased by a fibrotic endometriotic mass (* in D). (E) Axial T2-weighted MR image in a 37-year-old woman shows atrophy of the left iliopsoas (solid oval) and sartorius muscles (dashed oval), both innervated by the femoral nerve.
