How best to characterize CT lung findings after radiation therapy
By Kate Madden Yee
Serial chest CT is cornerstone of post-RT surveillance, but "accurate interpretation is critical to avoid misdiagnosis."
April 17, 2026
Acute radiation-induced pneumonitis after SBRT (65 Gy, four fractions) in a 53-year-old woman with leiomyosarcoma of the uterus with a left lower lobe metastasis manifesting as a small nodule (not shown). (A) Axial dosimetric reconstruction of a CT image obtained for SBRT planning shows the metastasis receiving the maximal isodose (6500 cGy). (B) Axial CT image obtained 12 months after completion of RT shows focal ground-glass and consolidative opacities confined to the treatment plan (arrow). Note that acute lung injury with SBRT typically manifests later than with conventional RT (i.e., >12 weeks after completion of therapy), and in 25% of patients, the first CT manifestations occur more than one year after completion of RT.
Working in low light: The cost for radiologists
By Claudia Tschabuschnig
A review links low-light work to health, performance, and workforce challenges, placing a typical radiology workday closer to indoor twilight than daylight.
April 13, 2026
Low-light clinical environments can create a constant twilight effect, raising questions about how such conditions shape attention, fatigue, and daily rhythms.
Photon-counting CT reveals plaque progression despite statins
By Claudia Tschabuschnig
Photon-counting CT has been praised for image quality and dose reduction. New HURRICANE study data show it can also track coronary plaque progression over time, revealing ongoing disease despite guideline-directed statin therapy.
April 8, 2026
'With photon-counting CT we can quantify plaque volume and its components objectively and track how they change over time,' said Mariaelena Occhipinti, MD, PhD, of Fondazione Gabriele Monasterio Regione Toscana CNR in Pisa, Italy.

When systems go down: Radiology under disaster
By Claudia Tschabuschnig
Most radiology disaster plans are stored on a server -- and most servers go down in a disaster.
April 6, 2026
'Disasters remind us that radiology is not only about imaging. It is about decisions, responsibility, and humanity,' said Prof. Nursel Yurttutan, MD, of Kahramanmaras Sutcu Imam University in Kahramanmaras, Turkey.

Calcium, cash, and cardiovascular reckoning: Can Europe's new heart plan deliver?
By Claudia Tschabuschnig
A new EU strategy promises to shift cardiovascular care from reaction to prevention, but funding gaps, underused imaging data, and a media attention paradox are already testing its ambitions.
April 2, 2026
'If we continue to spend public money treating diseases rather than investing in prevention, we risk getting nowhere,' said Romana Jerković.

ECR: The scan you've already done: Body composition's missing picture
By Claudia Tschabuschnig
The argument for body composition in radiology is not about acquiring new data, but about reading what's already there. At ECR 2026, two sessions made the case that every CT scan already holds information that could change a patient's prognosis. Most of it is never reported.
March 25, 2026
'We can see what the clinicians cannot see, and especially sarcopenia and osteoporosis are under-reported and under-diagnosed,' said Kerensa Beekman, MD, PhD, of Radboud University Medical Center.

Identifying CAD risk over time: A SCOT-HEART trial analysis
By Maryam Payne
One-third of patients with initially normal CCTA imaging developed CAD during the SCOT-HEART study’s 10-year follow-up period.
March 12, 2026
Development of CAD in a 43-year-old male smoker, with atypical chest pain, hypercholesterolemia, and a family history of CAD. At baseline, the coronary artery calcium score was zero (A), and the coronary CT angiogram was normal (B). Noncontrast CT chest (C) 10 years later showed calcified plaques in the right coronary artery and left circumflex coronary artery.
