Video from ECR 2019: Nicola Strickland on Brexit & radiology

Feb 27, 2019

The planned withdrawal of the U.K. from the European Union is due to take place on 29 March, and it is having a major impact on the recruitment and retention of staff and the supply of medical isotopes. Dr. Nicola Strickland, the president of the Royal College of Radiologists (RCR), elaborates on what RCR is doing to alleviate the situation.

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.

Is it time to ditch physical exams before ultrasound?

By Amerigo Allegretto

Physical exams are omitted in over half of patient cases, and it seems diagnostic outcomes are unaffected.

What prompts radiology department cancellations of imaging orders?

By Kate Madden Yee

Although the percentage of radiology cancellations of imaging orders is low, these cancellations are influenced by particular factors.

AI model detects achalasia on chest x-rays

Currently, few noninvasive tests are available for diagnosing the swallowing condition.

September 18, 2025

Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).

Echogenic rind on breast ultrasound holds diagnostic significance

By Amerigo Allegretto

An echogenic rind on breast ultrasound could spell malignancy for suspicious lesions.

September 17, 2025

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
