Study: DR delivers lower radiation dose
A new study by Italian researchers has found that digital radiography (DR) delivers lower radiation dose to patients than either conventional x-ray or computed radiography (CR) systems. In comparison to CR, DR delivers nearly half the radiation dose of the competing digital modality.

Ultrasound
Active thyroid surveillance effective, beneficial for older patients
Active surveillance with ultrasound and pathology is effective for patients with early-stage thyroid cancer, especially older ones.
A 58-year-old woman was diagnosed with ER-positive (Allred score 8) ILC in her right breast. Ultrasound and MRI found prominent lymph nodes in right axillary level I area, diagnosed as metastasis on ultrasound-guided fine-needle aspiration. F-18 FES-PET/CT showed a positive mass in right breast (white arrow; SUVmax, 5.6) and multiple F-18 FES–positive lymph nodes in right axillary level I, II, and II/III junction areas (red arrows; SUVmax, up to 12.2). In addition, a small F-18 FES-positive lymph node was observed in the right second internal mammary area (red circles; SUVmax, 1.8). However, biopsy could not be performed because it was too small and not visible on ultrasound; the clinician decided to include internal mammary lymph node in treatment field for adjuvant radiotherapy. The patient underwent lumpectomy with ALN dissection, with five metastases being identified in 13 lymph nodes dissected, and is scheduled to receive adjuvant chemotherapy, radiotherapy, and endocrine therapy.

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

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.
