Last-Minute Tips to Revise Radiology for NEET PG 2026
Radiology revision should be image-based, sign-oriented, and clinically integrated. In the last few weeks before NEET PG, avoid reading lengthy theory and focus on high-yield images, classic signs, best investigations, emergency imaging, and PYQs.
-
Revise classic images daily
Radiology is highly image-based. Revise chest X-rays, CT brain, abdominal X-rays, bone tumour X-rays, ultrasound images, and MRI findings daily.
-
Focus on emergency radiology
Emergency imaging is repeatedly asked. Revise extradural hematoma, subdural hematoma, pneumothorax, pneumoperitoneum, intestinal obstruction, renal colic, stroke, and pulmonary embolism.
-
Memorise the best investigation tables
Many questions ask about the best initial or preferred imaging modality. Make a quick table for stroke, trauma, gallstones, renal stones, pregnancy, PE, appendicitis, and disc prolapse.
-
Learn radiological signs with conditions
Classic signs are high-yield. Revise coffee bean sign, double bubble sign, apple core lesion, sunburst appearance, onion-skin appearance, soap-bubble appearance, and bat wing appearance.
-
Practice CT brain interpretation
CT brain findings are common in NEET PG. Revise extradural, subdural, subarachnoid, intracerebral haemorrhage, infarct, oedema, and hydrocephalus.
-
Revise the chest X-ray systematically
Practice reading trachea, lungs, pleura, heart size, mediastinum, diaphragm, bones, and soft tissues in every chest X-ray.
-
Do not skip radiation safety
Radiation protection, pregnancy precautions, contrast safety, and the ALARA principle are commonly asked as direct questions.
-
Solve PYQs thoroughly
PYQs help identify repeated radiological signs and image patterns. After every PYQ, revise the modality, diagnosis, radiological sign, and next best investigation.
