MRI touted for SPECT's role in sizing infarcts
A new report in Radiology is only the second published study of human patients that compares the accuracy of delayed enhancement (DE) MRI versus a nuclear imaging technique for estimating the size of acute infarcts.

Study validates cheap and easy method for atherosclerosis screening
A new study has found that aortic atherosclerosis can be accurately predicted by measuring the compliance or stiffness of arteries in a patient's leg -- an approach that could trump CT coronary calcium scanning for identifying subclinical heart disease.

Radiologists install PET/CT despite community opposition
When a committee that includes your three biggest payors recommends against your installing a PET/CT scanner, do you go ahead anyway? The question is one of several raised in connection with events in upstate New York that some say are leading to an "arms race" in imaging.

US diagnosis of vasa previa prevents perinatal mortality
Researchers have found that a prenatal diagnosis of vasa previa -- an obstetrical condition that historically resulted in 95% fetal mortality -- can reverse expected outcomes to achieve nearly 100% fetal survival.

Nailed in the head: X-ray, CT show patient's good luck
When the patient arrived at Providence Holy Cross Medical Center in Mission Hills, CA, it was clear he'd need more than an x-ray. Plain films were able to answer an immediate question: How many nails had been driven into his head? His physicians then turned to 3D CT images to gauge the extent of the injury and guide treatment.

Radiologists seek to optimize PICC line placement
Peripherally inserted central catheters have been a fast-growing part of medicine for more than a decade now, with hospital radiologists playing a critical role in confirming the placement of these devices. Yet despite years of experience, a globally standardized approach to imaging of PICC placements remains elusive.

When it comes to confirming the placement of peripherally inserted central catheters (PICCs), should radiology departments strive to use fluoroscopy rather than radiographs?

Low-dose CT ties emphysema to mortality in previous smokers
By Amerigo Allegretto
Study findings highlight the clinical relevance of CT-diagnosed emphysema.
September 9, 2025
Representative axial images of mild, moderate, and severe emphysema at baseline low-dose CT (LDCT). Participants were categorized as having no emphysema or mild, moderate, or severe emphysema. When present, emphysema was mild if no distinct regions of reduced attenuation were visible on the CT scan, but vascular splaying indicates parenchymal expansion, or if only occasional discrete low-attenuation regions were observed. Moderate emphysema was defined by the presence of identifiable low-attenuation regions affecting less than half of the lung parenchyma, whereas severe emphysema was defined by the presence of identifiable low-attenuation regions that involved more than half of the lung parenchyma. A scoring system from 0 to 3 was applied, corresponding to none, mild, moderate, and severe emphysema, respectively. Yellow circle indicates the extent of emphysema. (A) A 67-year-old man with mild emphysema at baseline LDCT in 2002. Baseline LDCT scan shows vascular splaying, suggesting parenchymal expansion due to emphysema and occasional discrete low-attenuation regions. The participant ultimately died of cardiovascular disease 15.4 years (184.2 months) later. (B) A 69-year-old man with moderate emphysema at baseline LDCT in 2007. The participant died of cardiovascular disease 1.8 years (21.9 months) later. Identifiable low-attenuation regions affected less than half of the lung parenchyma. (C) An 85-year-old woman with severe emphysema at baseline LDCT in 2006. After 5.5 years (65.5 months) of follow-up, the participant died due to chronic obstructive pulmonary disease–related causes. Identifiable low-attenuation regions involved more than half of the lung parenchyma.

I-123 MIBG–negative and F-18 MFBG–positive scans showing multiple lesions in 9-year-old male with relapsed high-risk, multiple-relapse neuroblastoma (stage IV disease) receiving chemoimmunotherapy. (A) I-123 MIBG uptake is seen in lower lumbar vertebrae (arrows). Positive uptake with F-18 MFBG PET (B; black arrows) in skull, spine, pelvic bones, femora, and left tibia (B and C; blue and white arrows). Bone marrow biopsy was positive for disease. Follow-up I-123 MIBG imaging (D; left) and spine MRI (D; right) performed six weeks later showed diffuse disease in skull and spine, corresponding to F-18 MFBG–avid sites.
