Men appear more vulnerable to dynamic carotid plaque
By Liz Carey
The population-based Rotterdam Study presented an opportunity to follow 802 participants, simulating plaque evolution over time.

Demonstration of colocalization of pre-existing calcification and incident intraplaque hemorrhage (IPH) in the same plaque. Axial cross sections of the same plaque at the same arterial location on a scan obtained with a T1-weighted gradient-echo noncontrast MRI sequence in a 70-year-old female participant who was free of coronary heart disease and stroke before follow-up MRI. Baseline (left) and follow-up (right) MRI examinations. The blue arrows highlight calcification in a hypointense signal area, while the green arrow indicates IPH as a hyperintense signal. The asterisks mark the lumen of the carotid artery.

PET/CT visualizes extremely rare brain inflammation
By Will Morton
An F-18 FDG-PET/CT scan proved crucial in identifying an ultrarare case of brain inflammation in a patient due to the flu.

Brain MRI and F-18 FDG brain and whole-body PET/CT images. (A) No obvious abnormalities were found in axial and sagittal slices from T2-weighted MR images. (B) Whole cerebellar cortex had diffuse F-18 FDG hypermetabolism in PET/CT brain images, with SUVmax of 25.91. (C and D) Whole-body F-18 FDG-PET/CT showing distended bladder. TLG = total lesion glycolysis; MTV = metabolic tumor volume. Image and caption courtesy of the Journal of Nuclear Medicine.

FCH-PET/CT superior to MIBI-SPECT/CT for guiding parathyroid surgery
By Will Morton
F-18 fluorocholine (FCH) PET/CT could be a first-line technique over technetium-99m sestamibi SPECT/CT for imaging parathyroid tumors prior to surgery.
June 20, 2024
(A) FCH-PET maximum-intensity projection; (B) FCH-PET/CT fusion transverse slice; and (C) low-dose CT transverse slice, showing high FCH uptake in an 11-mm left inferior parathyroid adenoma (arrowheads). The patient underwent minimally invasive parathyroidectomy, leading to normocalcemia during follow-up. No complications occurred.

Can PET help diagnose neurosarcoidosis?
By Will Morton
FDG-PET imaging shows promise for use as a diagnostic criterion for neurosarcoidosis, with a recent case series illustrating the approach was effective when gold-standard approaches were not, according to a group of researchers in Berlin.
