Reading a chest X-ray systematically: a practical ABCDE approach
A reliable, repeatable way to read every chest radiograph — and avoid the misses that come from jumping to the obvious finding.
Stroke imaging in the first hour: CT, CT angiography and perfusion
Time is brain. How a fast, protocol-driven imaging pathway identifies who can receive thrombolysis and thrombectomy.
Radiation dose in CT: putting the numbers in perspective
How much radiation does a CT scan really deliver, and how do we explain the risk honestly to patients?
Point-of-care ultrasound in the emergency department: what it can and cannot tell you
Bedside ultrasound answers focused yes-or-no questions fast. Knowing its limits is what makes it safe.
Interpreting high-sensitivity troponin in suspected acute coronary syndrome
A raised troponin means myocardial injury — not necessarily myocardial infarction. How to use serial values and rapid pathways.
Fever in infants under 90 days: a structured approach
Young infants with fever can look well and still have a serious bacterial infection. Age-based risk stratification keeps them safe.
Lung cancer screening with low-dose CT: who benefits?
Large trials show screening saves lives in high-risk smokers. The challenge is reaching the right people and managing what we find.

Recognising sepsis early: beyond the old SIRS criteria
Sepsis is organ dysfunction caused by a dysregulated response to infection. Spotting it early still depends on clinical vigilance.
A practical approach to hyponatraemia
The most common electrolyte disorder in hospital. Treat the symptoms, find the cause, and never correct too fast.
Pre-eclampsia: early recognition and the role of aspirin
A leading cause of maternal and perinatal harm. Risk assessment in early pregnancy allows effective prevention.
How to read a full blood count with confidence
The most ordered blood test holds more information than most of us use. A simple framework for every result.
Teaching case: intussusception in a nine-month-old, diagnosed on ultrasound
An illustrative case of intermittent colicky pain in an infant, and why ultrasound is the first-line test.
Tuberculosis on chest imaging: patterns every clinician should know
TB can mimic almost anything on a chest film. Recognising its main patterns speeds diagnosis and protects others.
Hypertension control in primary care: closing the gap
Most people with high blood pressure are not adequately controlled. Simple system changes make the biggest difference.
Acute appendicitis: choosing the right imaging for adults, children and pregnancy
The best first test depends on who is in front of you. A practical guide to ultrasound, CT and MRI.
