PET/MRI may help diagnose fevers of unknown origin
By Will Morton
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
By Will Morton
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
By Kate Madden Yee
MRI could help clinicians assess neural involvement in endometriosis and help prevent irreversible nerve damage and chronic sensorimotor neuropathy.
January 4, 2024
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.

CEFUS visualizes carotid plaque volume
By Amerigo Allegretto
3D contrast-enhanced fusion ultrasound (CEFUS) can analyze carotid plaque volume burden and could help monitor plaque development over time.
January 4, 2024
Segmentation of the carotid artery included the reconstruction of the carotid artery from 3D CEFUS/3D CTA to enable volume quantifications. (a) Only shown for 3D CEFUS, a 3D cylindrical model was initialized from manually set circle marks of the vessel wall border (media-adventitia interface) in the common carotid artery and internal carotid artery. From the circles, a mesh of the vessel border (yellow delineation) was formed. (b) The contour of the contrast-filled lumen was outlined (red delineation), creating a lumenography into the final reconstructed 3D carotid model. The same segmentation procedure was performed on the corresponding 3D CTA. The images are available to use under a Creative Commons license: CC BY 4.0 DEED, Attribution 4.0 International.
