There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis. This is an illustrative example of a relevant dissemination investigation.

T2-weighted MRI shows promise for body composition analysis

1Each lung has been split into three parts. Each area has been given a score between 0 and 3. Score values are shown in Ultrasonograms to match 4 different patterns. During a longitudinal scan with a high-resolution linear probe, pictures of patterns were taken. The scores are as follows: 0 means A pattern, 1 means B pattern, 2 means severe B pattern, and 3 means extended consolidation.

PSMA-PET tracer performs well in clinical trial

PET/CT imaging with a new gallium-68-based prostate cancer radiotracer shows promise for detecting recurrent metastatic disease.

(A) Representative maximum-intensity projection and selected PET/CT images (fused, PET and CT only) of patient with metastatic prostate cancer at 1 hour after injection. (B and C) Low uptake of Ga-68 PSMA-R2 in salivary and submandibular glands is also demonstrated. (D) Images show heterogeneous uptake of Ga-68 PSMA-R2 with varying degrees of intensity in multiple spine bone lesions (vertebral sclerotic lesion with intense PSMA-R2 expression at its periphery indicated with red arrow).

ACS: Fewer Black men are dying from cancer

Black men in the U.S. between the ages of 40 and 59 experienced a 65% to 67% decline in cancer mortality between 1999 and 2022, according to 2025 ACS statistics.

Are white-matter hyperintensities found on MRI biomarkers for TBI?

By Kate Madden Yee

White-matter hyperintensities found on high-resolution FLAIR images on 3-tesla MRI aren't necessarily biomarkers for mild traumatic brain injury (TBI).

Epicardial adipose tissue on LDCT tied to cardiovascular mortality risk

By Amerigo Allegretto

Epicardial adipose tissue (EAT) on low-dose CT (LDCT) images is tied to higher cardiovascular mortality risk in lung cancer patients.

February 18, 2025

Epicardial adipose tissue (EAT) segmentation (shading) at noncontrast chest CT in axial orientation. Representative examples show EAT changes (ΔEAT) between baseline and two-year follow-up CT scans in participants who survived (typical changes) and increasing and decreasing EAT in participants who died.

7-minute shoulder MRI scans are feasible

A commercially available deep-learning (DL) algorithm can enable high quality seven-minute shoulder MRI exams.

February 18, 2025

Images in an 18-year-old man with recurrent dislocations of the right shoulder. (A, B) Unenhanced coronal, (C) axial, and (D, E) sagittal deep learning super-resolution threefold parallel imaging -- accelerated turbo spin-echo MRI scans were obtained at 3-tesla field strength. (A) Coronal T2-weighted fat-suppressed (FS) and (B) coronal proton density (PD)-weighted MRI scans show a nondisplaced superior labral tear (arrows). (C) Axial proton density-weighted fat-suppressed, (D) sagittal T2-weighted fat-suppressed, and (E) sagittal T1-weighted MRI scans show continuation into a nondisplaced anteroinferior labral tear (arrows). All seven readers correctly diagnosed the arthroscopy-validated findings. (F) An arthroscopic photograph shows the anteroinferior labral tear (arrow). Image and caption courtesy of the RSNA.
