A 50-year-old with altered mental status had a non-contrast head CT reported as normal. CT angiogram revealed a focal occlusion of the distal basilar artery extending into the right P1 segment, with non-opacification of the proximal left PCA and left vertebral artery. DSA confir…
A 49-year-old with left homonymous hemianopsia had an unremarkable non-contrast head CT. CT perfusion revealed right PCA territory penumbra (Tmax mismatch), and CTA confirmed a focal P1-P2 junction occlusion. Post-treatment MRI showed a small right hippocampal infarct.
Chest X-Ray - Basic Interpretation
Eurorad teaching case presents medullary cap dysplasia, a rare congenital spinal cord anomaly, and its association with spinal dysraphism. Recognizing this entity on MRI can prevent misdiagnosis.
A short educational video from Navigating Radiology provides a simple explanation of Hounsfield units (HU), the standardized scale used in CT to quantify tissue density. Aimed at radiology residents and medical students, it covers how water is 0 HU and why the scale matters for…
Educational stroke imaging case: 72yo with right weakness, CT shows left insular hypodensity, CTP small core with large penumbra, DSA confirms distal M1/M2 occlusion. Successful thrombectomy. Part of a 4-case intro series.
Educational short reviews the arterial territories of the brain: ACA (anterior frontal), MCA (lateral frontal, parietal, temporal), PCA (medial parietal, occipital, temporal), and SCA (superior, medial cerebellum). A quick reference for recognizing vascular patterns on imaging.
In a retrospective study of 230 women with BI-RADS 4 lesions, positive predictive value (PPV) was 26.9%. Subcategory PPVs: 4A 18.7% (exceeding typical 2-10%), 4B 27.6%, 4C 50%. History of breast cancer increased malignancy risk (34.9% vs 21.5%, p=0.001).
Noncontrast CT, CTA, and CT perfusion in a 66-year-old with dysarthria showed a right frontal infarct with a small core but large penumbra from an ICA occlusion; thrombectomy salvaged the at-risk tissue.
DWI-positive/FLAIR-negative mismatch on MRI suggests wake-up stroke symptom onset within 4–6 hours, potentially indicating eligibility for aggressive therapy.
A new educational series on stroke imaging begins with a primer on patient presentation (focal neurologic deficits like weakness, aphasia, vertigo) and how CT and CT perfusion are used in the initial evaluation.
New educational short video from Navigating Radiology breaks down how different shades of gray on CT correspond to tissue densities (e.g., bone, fluid, fat, air), helping learners quickly interpret scans.
Key stroke imaging timelines: CT perfusion detects abnormalities near-immediately (<30 min). DWI turns positive at 30-60 min. FLAIR changes appear at 4-6 h. Noncontrast CT becomes abnormal at 6-24 h. Postcontrast enhancement is seen at 2-3 days. A quick reference for image inter…
A short, humorous educational vignette highlights common, non-clinical pitfalls in radiology workflow—like network and PACS failures—that disrupt reading efficiency. It serves as lighthearted, relatable training for residents and trainees navigating the daily technical frustrati…
Contrast-enhanced MRI is highly sensitive for detecting perineural and leptomeningeal tumor spread. This video with Dr. Katie Bailey shows key imaging features and differences, using case examples.
A Eurorad teaching case reports that combined renal artery and vein recanalisation successfully restored kidney function following post-surgical occlusion.
This Eurorad teaching case highlights the MRI features of Coats plus syndrome, emphasizing 'rings and blooming' as diagnostic clues. It serves as a visual walk-through for radiologists encountering this rare neurocutaneous disorder.
Free comprehensive video tutorial on knee MRI from Navigating Radiology, covering sequences, labeled anatomy, and a systematic approach to each structure. Includes case-based modules with AI hints and feedback to learn common pathologies.
On ultrasound, common bile duct (CBD) stones may lack posterior shadowing; use twinkling artifact and a dilated CBD (>6 mm, +1 mm per decade >60 years) as key clues. Seen in up to 15% of patients with gallstones, complications include cholangitis and pancreatitis.

Focal nodular hyperplasia (FNH) is a benign liver tumor with no malignant potential, requiring no surgery—a true 'leave alone' lesion. CEUS aids diagnosis. Most common in women aged 20-50, with an 8:1 female-to-male ratio, and no link to oral contraceptives.
