CT Scan of Lower Abdomen (including Pelvis) with Contrast

What is the CT Scan of Lower Abdomen (Including Pelvis) With Contrast?

The test combines X-ray technology and computer processing to create cross-sectional images. A special iodine-based contrast dye is injected into a vein in your arm. The dye highlights blood vessels and soft tissues, making even small abnormalities easier to see. Key points at a glance:

• Duration: 10–20 minutes
• Positioning: You lie on your back on a motorized table.
• Noise level: A soft whirring sound; earplugs are available on request.
• Radiation: Low-dose protocols are used at Cadabams Diagnostics to keep exposure minimal.

When and Who Needs to Take This CT Scan?

Doctors frequently recommend the scan for adults and children who experience:

• Persistent lower abdominal pain or pelvic pain
• Blood in stool or urine
• Suspected kidney stones, appendicitis, or diverticulitis
• Unexplained weight loss
• Follow-up after cancer treatment
• Trauma after an accident

A CT scan of lower abdomen (including pelvis) with contrast is a fast, painless imaging test that gives your doctor a detailed 360-degree view of your intestines, kidneys, bladder, reproductive organs, blood vessels, and lymph nodes. If you have unexplained pain, bleeding, or abnormal blood tests, this scan can pinpoint the cause quickly and accurately.

The radiologist evaluates:

• Bowel wall thickness
• Liver, spleen, and pancreas texture
• Kidney size and cortical thickness
• Ureter and bladder diameter
• Uterus or prostate size and contour
• Lymph-node size
• Any abnormal masses or fluid collections

• Detect tumors or cysts in ovaries, uterus, prostate, or bladder
• Diagnose appendicitis, diverticulitis, or abscesses
• Stage cancers (colorectal, cervical, bladder)
• Guide biopsies or surgery
• Monitor treatment response

• Sharper images of soft tissues compared to X-rays
• Faster diagnosis: Results often ready within hours
• Non-invasive: No scopes or incisions
• Out-patient procedure: Return home the same day

• Inflammatory bowel disease (Crohn’s, ulcerative colitis)
• Kidney stones and hydronephrosis
• Appendicitis and diverticulitis
• Ovarian or uterine cancer
• Prostate enlargement or cancer
• Abdominal abscesses or infections

Pre-requisites

• Bring doctor’s prescription and previous imaging if any
• Wear loose, metal-free clothing
• Remove jewelry, belts, and piercings

Best Time to Take the CT Scan

Morning slots are preferred because:

• Easier fasting overnight
• Quicker access to follow-up care if needed

Eligibility

• Adults and children (sedation available for kids)
• Pregnant women: scan only if absolutely necessary and after risk–benefit discussion
• Kidney function: eGFR >30 mL/min/1.73 m² usually required

Procedure for Taking the CT Scan

1. Check-in: Registration and consent form
2. Contrast: IV line inserted; dye may feel warm for 30 seconds
3. Positioning: Lie still; you may be asked to hold your breath for 5–10 seconds
4. Scan: Table moves through the scanner ring once or twice
5. Observation: 10-minute rest to watch for any delayed reaction

Caution Before Taking the CT Scan

• Fasting: 4–6 hours for solids, 2 hours for clear fluids
• Medications: Take regular medicines with a sip of water unless told otherwise
• Allergies: Inform staff about shellfish or iodine allergies so pre-medication can be arranged

Types of CT Scans for Abdomen and Pelvis

• Contrast-enhanced CT: Most common; dye highlights vessels and organs.
• Non-contrast CT: Used mainly for kidney stones.
• CT enterography: Specialized for Crohn’s disease; you drink extra oral contrast. At Cadabams Diagnostics, the radiologist chooses the technique best suited to your symptoms.
