PET/MRI findings ‘encouraging’ for people with late-life depression

PET/MRI scans have revealed positive findings for people with late-life depression – namely that they have preserved “synaptic density,” and thus are likely to respond to treatment, according to a group in Belgium.

Multiparametric ultrasound in a 52-year-old female patient with metabolic dysfunction-associated fatty liver disease (MAFLD) and hepatitis B, whose body mass index was 26.9. (A) Gray-scale image (left) shows the liver parenchyma, and attenuation image (right) shows the right liver lobe acquired from the right intercostal oblique plane, with the degree of attenuation color-coded in the sampling box. Orange indicates a high attenuation coefficient and blue indicates a low attenuation coefficient. The coefficient value (0.59 dB/cm/MHz) and reliability index (R2 = 0.95) are presented in the lower left corner. (B) 2D shear-wave elastography-generated quad-view mode image shows an elasticity map, propagation map, gray-scale image, and dispersion map at the same time. A 1-cm region of interest is placed within the sampling box of each image. Red and blue indicate high and low elasticity and dispersion slope, respectively. Liver stiffness on the elasticity map is 5.6 kPa, and the dispersion slope on the dispersion map is 13.23 (m/sec)/kHz. Image courtesy of the RSNA.

FAPI-PET/CT outperforms FDG-PET/CT in women with invasive breast cancer

PET/CT imaging using gallium-68 FAPI radiotracer over F-18 FDG appears promising in women with invasive lobular carcinoma.

Maximum-intensity projection F-18 FDG-PET (left) and Ga-68 FAPI-PET (right) images of synchronous ILC. (A) A 42-year-old patient with multicentric primary lesions (encircled), regional (solid arrows), and distant inferior jugular lymph node (dashed arrows) seen on F-18 FDG-PET and subsequently confirmed on Ga-68 FAPI-PET, which also revealed additional malignant foci aligned with MRI. Some lesions exhibited high activity retention on Ga-68 FAPI-PET. (B) A 53-year-old patient showing no significant uptake on F-18 FDG-PET but synchronous bilateral lesions (arrows) on Ga-68 FAPI-PET, which also identified pathologic lymph nodes (encircled), resulting in upstaging.
