About The Test
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.
CT Lower Abdomen (Including Pelvis) Without Contrast – Overview
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.
What Is CT Lower Abdomen (Including Pelvis) Without Contrast?
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
When & Who Needs CT Lower Abdomen (Including Pelvis) Without Contrast?
| Clinical Indication | Typical Symptoms |
|---|---|
| Kidney stones | Flank pain, blood in urine |
| Appendicitis | Right-lower-quadrant pain, fever |
| Diverticulitis | Left-lower-quadrant pain, altered bowel habits |
| Trauma | Abdominal pain after injury |
| Bowel obstruction | Severe cramps, vomiting, distension |
| Age & Health Eligibility: Adults and children ≥5 years; safe for pregnant women only when benefits outweigh risks. |
List of Parameters
- 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
Why This Test
- Rapid triage in emergency settings
- Avoid contrast complications for fragile kidneys
- Cost-effective single test for multi-system screening
When to Take Test
Benefits
Benefits of Taking the Test
✓ 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
Illnesses Diagnosed with CT Lower Abdomen (Including Pelvis)
- Kidney & ureteric stones
- Appendicitis, diverticulitis
- Bowel obstruction / perforation
- Pelvic fractures & hemorrhage
- Hernias & abscesses
Preparing for test
- 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).
Pre-Requisites
- Creatinine report if eGFR unknown or history of renal disease.
- Previous imaging CDs/reports for comparison.
Best Time for the Scan
- Early morning slots: Shorter wait times.
- 24/7 availability for emergencies at Cadabams Diagnostics.
Eligibility
| Group | Eligibility |
|---|---|
| Adults | All ages |
| Children | ≥5 years |
| Kidney disease | Yes, if creatinine ≤1.5 mg/dL or dialysis planned |
| Pregnancy | Only if medically necessary; fetal shielding provided |
Step-by-Step Procedure
- Registration & ID verification
- Change into gown & secure valuables
- Lie on CT table, feet-first; arms above head
- Single breath-hold for each scan series (5–10 minutes total)
Cautions Before Scanning
- Notify the technologist if you are or might be pregnant.
- Disclose implanted devices: cardiac pacemakers, surgical clips, joint prostheses.
Test Results
Results and Interpretations
| Finding / Observation | Description | General Interpretation/Significance |
|---|---|---|
| Parameter | Normal | Likely Interpretation |
| Kidney length | 9–12 cm | <9 cm or >12 cm | Atrophy or hydronephrosis |
| Appendix diameter | ≤6 mm | >6 mm | Appendicitis | |
| Free fluid | None | Present | Bleeding or infection |
Risks & Limitations
- 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.
Types of CT Lower Abdomen (Including Pelvis) Without Contrast
- Standard helical CT: 1–2 mm slice thickness; routine evaluation.
- Low-dose protocol: 30–50 % less radiation; ideal for follow-up stone cases.
- High-resolution mode: 0.5 mm slices for detailed bone and soft-tissue assessment.
FAQs
Is the radiation dose safe?
Yes, it equals ~6 months of natural background exposure and is well within safe limits.
Can I drive afterward?
Absolutely—no sedation is involved.
How soon will I get results?
Same day; urgent cases within 30 minutes.
Do I need a doctor’s prescription?
Yes. Bring a signed requisition or have your physician email it to
When will I receive my results?
At Cadabams Diagnostics, we pride ourselves on a quick turnaround. For urgent cases, a preliminary report can often be made available to your doctor shortly after the scan. A final, detailed report is typically ready within 24 hours.
What is the main difference between this scan and one with contrast dye?
The main difference is the use of an iodine-based intravenous (IV) dye. A CT Lower Abdomen without Contrast does not use dye and is excellent for seeing bones and calcifications like kidney stones. A scan with contrast uses dye to make blood vessels and certain organs or abnormalities stand out more clearly, which is better for evaluating tumors, infections, or vascular problems.
