Stomach Pain Causes: When Your Doctor Recommends a CT Abdomen Scan

When Stomach Pain Is More Than Just Acidity

Stomach pain is something every person in Ahmedabad has experienced. The dull ache after a heavy Gujarati thali. The sharp cramps of a stomach infection. The familiar burn of acidity that a Digene tablet usually fixes. For the vast majority of episodes, the pain is benign, self-limiting, and nothing to worry about.

But then there is the other kind. The pain that doesn't go away. The pain that wakes you up at night. The pain that is getting progressively worse over days. The pain that is accompanied by fever, vomiting, blood in the stool, or a lump you can feel. This is the kind of stomach pain that your doctor does not treat with antacids — this is the kind that leads to a prescription for a CT abdomen scan.

A CT abdomen is the most powerful, comprehensive diagnostic tool available for evaluating the abdominal cavity. In a single 10–15 minute scan, it provides your gastroenterologist, surgeon, or emergency physician with a detailed cross-sectional view of every major organ and structure from the diaphragm to the pelvis — stomach, liver, gallbladder, bile ducts, pancreas, spleen, both kidneys, the bowel, the aorta and its branches, lymph nodes, and the bladder. At Usmanpura Imaging Centre, we perform CT abdomen scans around the clock with same-day reports read by specialist abdominal radiologists.

Where Is Your Pain? — Anatomy of the Abdomen

Before your doctor decides which investigation to order, they localise your pain. Different organs occupy different regions of the abdomen, and the location of pain is one of the most important clues to its cause. Here's the map your doctor uses — and which organs a CT scan would evaluate for each region:

The Most Common Causes of Stomach Pain That Require a CT Abdomen

Not every stomach pain needs a CT scan. But there are specific conditions — serious enough to require accurate diagnosis before treatment — where a CT abdomen is the investigation your doctor will reach for first or second. Here are the most common:

When Does Your Doctor Order a CT Abdomen? — The Decision Guide

Doctors use a systematic approach to decide whether to order a CT abdomen. Here's the clinical reasoning behind the most common scenarios:

CT Abdomen vs Ultrasound — Why Doctors Sometimes Upgrade

Many patients come to us having already had an ultrasound of the abdomen. They ask — if the ultrasound showed something (or nothing), why does my doctor now want a CT scan? Here's the clear-cut answer:

The two tests are complementary — not competing. A normal ultrasound does not rule out serious pathology in the retroperitoneum, bowel, or mesentery. When a doctor orders a CT after an ultrasound, they are not doubting the ultrasound — they are getting a second, more detailed layer of information that ultrasound cannot provide.

What Happens During a CT Abdomen Scan at Usmanpura Imaging Centre?

Many patients have anxiety about CT scans — particularly about the contrast injection and what it feels like. Here is an honest, step-by-step walkthrough of exactly what to expect:

Understanding Your CT Abdomen Report — Key Terms Explained

CT abdomen reports use medical terminology that can be confusing. Here are the most common terms you are likely to encounter:

• Hepatomegaly — enlarged liver. May indicate fatty liver, hepatitis, heart failure, or malignancy depending on context
• Fatty liver / Hepatic steatosis — fat accumulation in liver cells. Graded mild, moderate, or severe. Reversible with lifestyle changes if caught early
• Cholelithiasis — gallstones. CT may miss small stones that USG detects better, but detects complications well
• Cholecystitis — gallbladder wall inflammation, typically with a surrounding fluid halo on CT
• Choledocholithiasis — stone in the bile duct (CBD) — causes jaundice and requires urgent ERCP or surgery
• CBD dilation — common bile duct is dilated, suggesting obstruction by stone, stricture, or tumour
• Pancreatitis — Balthazar grade — CT grading system for acute pancreatitis severity. Grade A–B = mild; C–E = severe with increasing necrosis
• Perinephric stranding — haziness around the kidney — typically indicating inflammation from infection or an obstructing stone
• Hydronephrosis — swelling of the kidney due to blocked urine flow. Graded mild, moderate, or severe
• Free fluid in abdomen — fluid in the peritoneal cavity — can indicate infection, bleeding, ascites, or bowel perforation
• Pneumoperitoneum — free air in the abdomen — indicates bowel perforation and requires emergency surgery
• Lymphadenopathy — enlarged lymph nodes — can indicate infection, lymphoma, or metastatic cancer depending on location and appearance
• Heterogeneous mass / Hypodense lesion — a lesion of mixed or lower density compared to surrounding tissue. Requires further characterisation — may be benign or malignant
• Ascites — fluid accumulation in the abdomen — can be caused by liver cirrhosis, heart failure, malignancy, or TB
• Mesenteric fat stranding — haziness in the fat around the bowel — indicates localised inflammation, as seen in appendicitis, diverticulitis, or epiploic appendagitis

How to Prepare for a CT Abdomen Scan — Practical Checklist

• Fast for 4–6 hours before a contrast-enhanced CT abdomen — a light meal is fine up to 4 hours before. Plain CT without contrast requires no fasting
• Drink plenty of water before and after the scan — good hydration helps protect kidney function and aids contrast clearance
• Bring your serum creatinine blood test — this is essential for assessing kidney function before contrast injection. If you don't have a recent result, our team can advise
• Inform us if you are diabetic and on Metformin — it should be withheld for 48 hours after a contrast CT scan
• Inform us of any previous allergic reaction to iodine-based contrast or seafood allergy
• Bring all previous abdominal scan reports and images — comparison is invaluable for the radiologist
• Tell us about all current medications — particularly blood thinners and immunosuppressants
• For female patients — inform us if you are pregnant or may be pregnant. CT uses radiation and pregnancy changes the approach entirely
• Wear loose, comfortable clothing — you will be asked to remove your outer garments and wear a hospital gown

• Same-day reports for routine cases — typically within 2–4 hours. Urgent emergency reports prioritised
• Low-dose CT protocols — we use radiation dose optimisation without compromising diagnostic image quality, particularly important for younger patients and repeat scans
• Walk-in and appointment-based — for emergency cases, walk in directly. For elective scans, book online or by phone
• All abdominal imaging under one roof — USG abdomen, CT abdomen, MRI abdomen, and CT angiography — so if your CT finding needs follow-up with MRI, you don't travel to another centre
• Transparent, affordable pricing — no hidden charges, all-inclusive reporting and digital delivery
• Central Usmanpura location, Ahmedabad — easily accessible from Ellis Bridge, Navrangpura, Shahibaug, Kankaria, Sabarmati, and surrounding areas

Final Thoughts — Stomach Pain That Doesn't Resolve Deserves a Clear Answer

Most stomach pain in Ahmedabad is managed with rest, oral rehydration, and a light diet. But the pain that keeps coming back — the pain that's getting worse instead of better — the pain that woke you up at 2 AM — that pain deserves more than just another antacid prescription.

A CT abdomen scan doesn't just tell your doctor what's wrong. It rules out what's dangerous. It guides surgical decisions. It catches cancers before they've spread. It finds the source of an infection before it overwhelms your body. In emergency medicine, it is often the single scan that saves a life by giving the surgical team the information they need to act in time.

If your doctor has recommended a CT abdomen — or if you've been managing unexplained abdominal pain for weeks without a clear diagnosis — come to Usmanpura Imaging Centre. We will give you the answers your abdomen has been asking for. Same day. Every day.
