CT Lower Abdomen (including Pelvis)without Contrast

Non-invasive, quick, and highly accurate: learn everything about the CT lower abdomen (including pelvis) without contrast and how Cadabams Diagnostics makes the process simple.

What Is CT Lower Abdomen (Including Pelvis) Without Contrast?

A CT lower abdomen (including pelvis) without contrast is a cross-sectional X-ray study that captures detailed images of organs—from the lower edge of the liver down to the pelvic floor—without using iodine-based contrast dye.

How It Differs From Contrast-Enhanced CT

• No dye injection: Safer for patients with contrast allergies or kidney impairment.
• Faster process: Skip IV line placement and post-scan observation.
• Lower cost: Eliminates contrast material and associated nursing time.

Definition & Technology

Using a helical CT scanner, the machine rotates around the body, capturing thin axial “slices.” Advanced software reconstructs these into 3-D views, highlighting:

• Organs: liver, kidneys, bladder, uterus/ovaries or prostate.
• Structures: blood vessels, lymph nodes, bowel loops.

When Contrast Is Omitted

• Contrast allergy history
• eGFR <30 mL/min/1.73 m² (kidney dysfunction)
• Pediatric cases to minimize risk

1. Standard helical CT: 1–2 mm slice thickness; routine evaluation.
2. Low-dose protocol: 30–50 % less radiation; ideal for follow-up stone cases.
3. High-resolution mode: 0.5 mm slices for detailed bone and soft-tissue assessment.

• Organ size & morphology
• Calcifications – kidney, ureteric, or vascular stones
• Free fluid or air – perforation or hemorrhage
• Lymph node enlargement
• Bladder / uterine / prostate wall thickness or masses

• Rapid triage in emergency settings
• Avoid contrast complications for fragile kidneys
• Cost-effective single test for multi-system screening

✓ 3–5 minute scan time ✓ No needles, fasting, or oral prep ✓ Same-day report via secure e-mail or SMS link ✓ Safe for contrast-allergic or kidney-compromised patients

• Kidney & ureteric stones
• Appendicitis, diverticulitis
• Bowel obstruction / perforation
• Pelvic fractures & hemorrhage
• Hernias & abscesses

• Fasting: None required; light snack is okay.
• Clothing: Remove belts, zippers, jewelry; wear loose cottons or hospital gown.
• Pregnancy: Urine β-hCG screening for women 10–55 years (unless documented hysterectomy).

• Creatinine report if eGFR unknown or history of renal disease.
• Previous imaging CDs/reports for comparison.

• Early morning slots: Shorter wait times.
• 24/7 availability for emergencies at Cadabams Diagnostics.

1. Registration & ID verification
2. Change into gown & secure valuables
3. Lie on CT table, feet-first; arms above head
4. Single breath-hold for each scan series (5–10 minutes total)

• Notify the technologist if you are or might be pregnant.
• Disclose implanted devices: cardiac pacemakers, surgical clips, joint prostheses.

• Radiation: ~4–6 mSv (equal to 6 months of natural background).
• Contrast necessity: Small tumors or subtle infections may be missed without dye.
• False negatives: Early appendicitis or ischemic bowel may require additional imaging.
