Perfusion CT finds subtle liver toxicity in chemotherapy patients
A new study from China found that perfusion CT can detect and quantitatively assess microvessel changes associated with liver toxicity in chemotherapy patients. The results could help noninvasively assess early liver damage in cancer patients while obviating the need for a separate scan.

SHAPE II task force revising cardiac risk guidelines
The Houston-based Society for Heart Attack Prevention and Eradication (SHAPE), which wants to scrap population-based cardiac risk assessment in favor of imaging-based evaluation of each individual, said it will release new guidelines at the November American Heart Association meeting in Chicago.

Coronary calcium usually ignored on chest CT
Radiologists often fail to report coronary calcium detected on chest CT scans. By ignoring it, they miss not only the chance to detect potentially serious heart disease, but an important opportunity to evaluate the chances of lowering a patient's risk of heart attack with treatment.

Clinical study backs newly cleared VC CAD software
Backed by a study that shows high sensitivity and specificity in patients, a new computer-aided detection (CAD) scheme for virtual colonoscopy was approved last week by the U.S. Food and Drug Administration.

Lack of virtual colonoscopy coverage a barrier to screening
A survey of primary care patients who were offered but did not undergo colon cancer screening found that more than four-fifths would be willing to undergo virtual colonoscopy -- but not if they had to pay the entire cost out of pocket.

SoCal hospitals say patients got too much CT radiation
Two more hospitals in Southern California have admitted that patients undergoing perfusion CT brain scans last fall received excessive radiation doses, just as legislation that would require dose levels to be displayed on CT scanners won a vote in the state Assembly.

Combined PET/CT CAD improves lung nodule detection
Researchers in Japan have developed computer-aided detection (CAD) software that detects lung nodules in PET/CT images of lung cancer screening patients. Applying a combined CAD system to both modalities instead of CT or PET alone nearly doubled the number of solitary pulmonary nodules detected.

Hallan alta taza de cataratas en cardiólogos intervencionistas
Una nueva investigación de cardiólogos intervencionistas y enfermeras en Malasia revela una taza de incidencia de cataratas cinco veces más elevada que en el grupo de control, la cual implica que los límites de dosis de radiación son demasiado altos para proteger al personal.

High cataract rates found in interventional cardiologists
A new study of interventional cardiologists and nurses in Malaysia found five times the rate of cataracts in the group compared to controls, suggesting that current radiation protection thresholds may be too high to protect providers from harm.

AI spots unidentified brain tumor on PET imaging
By Will Morton
An AI algorithm designed for brain PET imaging found a glioblastoma in a patient that had gone undetected by physicians.
February 20, 2024
Baseline scan (A), segmentation results (B), and follow-up scan (C) from patient with molecular glioblastoma. Baseline MRI showed FLAIR hyperintensities in left thalamus and frontoparietal region (white arrowheads). In contrast to expert segmentation, in which only left thalamic region showed slightly increased uptake (red contour), AI algorithm identified additional frontoparietal lesion on baseline PET that subsequently progressed to contrast-enhancing and metabolically active lesion (red arrowheads).

ADC optimal cutoff reduces MRI-prompted breast biopsies
By Amerigo Allegretto
Applying point-of-care apparent diffusion coefficient (ADC) cutoffs from diffusion-weighted imaging could reduce MRI-prompted breast biopsies.
February 15, 2024
Apparent diffusion coefficient (ADC) measurements for benign and malignant BI-RADS category 4 or 5 lesions at MRI. (A, B) Benign BI-RADS category 4 lesion in a 55-year-old woman. (A) Dynamic contrast-enhanced MRI (DCE-MRI) scan shows a 12-mm, oval, circumscribed, homogeneous mass in the right posterior breast (arrow). (B) On the diffusion-weighted image, the lesion shows high diffusivity (arrow), with an ADC of 2.04 × 10-3 mm2/sec. Biopsy revealed benign fibroadenoma. (C, D) Malignant BI-RADS category 4 lesion in a 41-year-old woman. (C) DCE-MRI scan shows a 24-mm irregular, heterogeneous mass at the 3 o’clock position in the left breast (arrow). (D) On the diffusion-weighted image, the lesion demonstrates low diffusivity (arrow), with an ADC of 0.91 × 10-3 mm2/sec. Biopsy revealed invasive ductal carcinoma. All MRI scans are shown in the axial plane. (E) Box plot shows ADC measurements for 240 BI-RADS 4 and 5 lesions (63 malignant and 177 benign). Both prespecified optimal and conservative ADC cutoffs are indicated on the plot for reference: 1.53 × 10-3 mm2/sec (dashed line) and 1.68 × 10-3 mm2/sec (dotted line), respectively. All ADCs were calculated with maximum b value of 800 sec/mm2. The midline of each box shows the median value, and the box extends from first to third quartiles. The whiskers extend from the first and third quartiles to the smallest and largest values, respectively, if those values are within 1.5 times the IQR. If not, the length of the whiskers is limited to 1.5 times the IQR. Image courtesy of the RSNA.
