Radiology
Radiology is the use of imaging such as X-rays, CT and MRI to diagnose disease. A psychiatrist uses it to know when brain imaging is needed and how to read imaging reports in patients with new psychiatric symptoms or cognitive decline.

What is it?
Radiology covers imaging methods: plain X-rays, ultrasound, CT, MRI and nuclear medicine. Students learn how each works, its risks, and how to interpret common findings like pneumonia on chest X-ray or a stroke on CT.
It is often taught throughout clinical years rather than as one long posting.
For psychiatry, the key lesson is when imaging helps and when it does not: brain scans are not routine for every psychiatric patient, but they are vital in first-episode psychosis with unusual features, new cognitive decline or neurological signs.
Why does a psychiatrist need it?
Psychiatrists decide when to request brain CT or MRI, interpret reports showing atrophy, white matter changes, tumours or stroke, and recognise how imaging supports dementia diagnosis. They also need basic chest X-ray skills for physical health care.

Common questions
Do all psychiatric patients need a brain scan?
No. Scans are useful when there are neurological signs, unusual features, sudden personality change, or cognitive decline. They are not routinely needed for most mental illnesses.
Can a brain scan diagnose depression?
Not in routine practice. Research scans show group differences, but no scan currently diagnoses depression in an individual patient.
