Who should get CT Scan Single Limb Contrast done in Chennai?

Hepatitis B prevalence in Tamil Nadu is estimated at around 3 to 4%. NAFLD is also rising rapidly among Chennai's large young professional population due to sedentary IT-sector jobs, high-carbohydrate diets, and rising obesity rates in areas like OMR and T Nagar. CT Scan Single Limb Contrast is ordered as a standalone imaging study when doctors need clear pictures of one arm or leg. It is commonly requested for symptoms like pain, swelling, weak pulses, non‑healing wounds, or after trauma. NAFLD affects an estimated 25 to 35% of India's urban adults , the majority unaware. Regular liver testing in Chennai's residential areas including Kodambakkam and Ashok Nagar enables lifestyle intervention before irreversible scarring occurs. Patients recovering from hepatitis, those in alcohol recovery, and anyone with persistently unexplained fatigue also benefit from regular liver monitoring.

What conditions can CT Scan Single Limb Contrast help diagnose?

Very high ALT and AST (10–50× normal) with normal ALP suggests acute hepatocellular injury , viral hepatitis, drug toxicity, or ischaemia.

Persistently low albumin with elevated bilirubin indicates advanced cirrhosis.
