Only one-third of patients received osteoporosis medication after vertebral augmentation. The incidence of new vertebral fractures fell from 0.519 to 0.076 per person-year after starting medical management (incidence rate ratio 6.79, 95% CI 3.37-15.51), a 6-fold decreased risk.
Percutaneous MWA of T1 RCC showed 76% 10-year overall survival, 85% cancer-specific survival, and 83% local progression-free survival, with stable renal function and low complications.
Integrated model combining emphysema, Pi10, airway branch count, and clinical data detected undiagnosed COPD with AUC 0.83 (95% CI 0.80-0.86) in 5,014 lung screening participants, up from 0.69 for emphysema alone, reducing confirmatory spirometry referrals from 41% to 34%.
FAPI PET/CT showed 93.0% sensitivity vs 76.5% for FDG (p=0.002) in 176 patients with suspected HPB cancers. Nodal accuracy was 86.8% vs 71.1%. Dual-tracer approach did not improve accuracy. Prospective validation needed.

Review the classic chest radiograph and CT features of silicosis, including upper lobe predominant nodules and hilar/mediastinal eggshell calcifications, in this free educational case.
A stimulated echo is an MRI signal arising when three or more RF pulses are applied, forming an echo that does not obey the usual spin-echo or gradient-echo rules. It can cause artifacts or be harnessed for diffusion and functional imaging.
Eurorad (ESR teaching case platform) has posted a new teaching case, Case 14472. No further details available from this announcement.
This educational Q&A covers the principles of phase mapping in MRI, explaining how phase data is acquired, processed, and used clinically for applications such as flow quantification and susceptibility imaging.
A Eurorad teaching case highlights that a transient, splenial lesion of the corpus callosum can occur after discontinuing antiepileptic drugs. (SECONDARY coverage; primary case not reviewed.)
Zero-filling and apodization alter spectral integral values in noisy discrete Fourier-transform spectroscopy, directly impacting quantitative MRI measurements derived from peak areas.
Eurorad teaching case reviews imaging features of chronic recurrent multifocal osteomyelitis (CRMO) of the clavicle, emphasizing differentiation from infection and tumor.

MRI radiofrequency (RF) power emissions determine the specific absorption rate (SAR), which quantifies tissue heating. Understanding RF power limits is essential for preventing patient burns and ensuring safe scan protocols.
A new Eurorad teaching case illustrates the clinical and imaging features of hemihyperplasia, an asymmetric regional body overgrowth disorder that carries an increased risk of embryonal tumors and requires periodic surveillance.
A Eurorad teaching case highlights the imaging findings of a splenorenal shunt—a spontaneous portosystemic collateral in portal hypertension. Recognizing it on CT/MR aids in differentiating from other vascular anomalies and understanding its hemodynamic significance.

Half-Fourier Acquisition Single-shot Turbo Spin Echo (HASTE/SS-FSE) is a T2-weighted technique using partial k-space sampling to reduce echo train length, enabling faster breath-hold imaging. It balances speed against potential blurring.
Gibbs artifact appears as fine parallel lines adjacent to high-contrast boundaries on MRI, caused by insufficient sampling of high spatial frequencies during Fourier reconstruction. It is most conspicuous on T1-weighted images near fat–water or tissue–CSF interfaces and can mimi…
