Pelvic CT scan
A computed tomography (CT) scan of the pelvis is an imaging method that uses x-rays to create cross-sectional pictures of the so called the pelvic area (area between the hip bones) and the pelvic cavity.
CT scan of the pelvis is used for examine the contents of the pelvic organs for evidence of cancer, bleeding, and obstruction. Structures inside the pelvis cavity include the bladder, prostate and other male reproductive organs, female reproductive organs, lymph nodes, and pelvic bones. Sometimes pelvic CT scan performed in patients with abdominal CT.
Remember, CT scans do expose you to more radiation than regular x-rays. Having many x-rays or CT scans over time may increase your risk of cancer. But the risk from any one scan is small. You and your doctor should weigh this risk against the benefits of getting a correct diagnosis for your medical condition.
CT images (slices) are stored on a computer, viewed on a monitor, printed on film or recorded on CD. 3D models of the body area can be created by stacking the slices together.
Pelvic CT scan is also performed to:
- guide biopsies and other procedures ( abscess drainages, minimally invasive tumor treatments)
- plan for and assess the results of surgery (organ transplants)
- stage, plan and properly administer radiation treatments for tumors and monitor response to chemotherapy
How the pelvic CT scan is performed
Pelvic CT scan is performed in the radiology department scanning room. The patient lying flat (supine) on a CT table. The head is placed in a comfortable “docking pillow” and the CT scanner gantry (donut) passes over and around the patient to perform the scan. It travels over the patient from the iliac crest to the pubic symphysis to create the scan.
If necessary pelvic CT scan may be performed with oral and intravenous contrast. Sometimes this test performed in conjunction with abdominal CT.
The patient must be still during the exam, because movement causes blurred images and sometimes may be told to hold breath for short periods. The scan should take less than 30 minutes. Some people may have discomfort from lying on the hard table.
Indications for pelvic CT scan
CT rapidly creates detailed pictures of the body, including the pelvis and areas near the pelvis. Pelvic CT scan may be used to diagnose or detect:
- masses or tumors, including cancer (prostate or uterus)
- the cause of chronic pelvic pain
- injury to the pelvis (pelvic bones fractures, joints injuries)
Pelvic CT scan may also help:
- as navigation to the right area during a biopsy or other procedures
- for surgery planning
- radiation treatment planning for cancer or other malignant
Pelvic CT scan results interpretation
Radiologist interprets Pelvic CT scans. Results are considered normal if the organs of the pelvis that are being examined are normal in appearance.
Information is highly detailed pertaining to solid and hollow organs in the pelvis. In addition, the integrity of the bony pelvis can be attained. The presence of tumor, inflammation, hemorrhage, stones and infection can be ascertained.
Abnormal results may be due to:
- abscess (collection of pus)
- bladder stones
- broken bones
- cancer or other malignant
- • diverticulitis
How to prepare for the pelvic CT scan
Certain exams require a special dye to be delivered into the body before the pelvic CT scan starts. The contrast media helps certain pelvic areas show up better on the x-rays. You may be asked to drink an oral contrast solution.
- Contrast can be given through a vein (IV) in your hand or forearm. Or you may be asked to drink a liquid form of contrast. If contrast is used, you may also be asked not to eat or drink anything for 4 to 6 hours before the pelvic CT scan.
- Let your doctor know if you have ever had a reaction to contrast. You may need to take medicines before the test in order to safely receive this substance.
- Before receiving the contrast, tell your doctor if you take the diabetes medicine metformin (Glucophage) because you may need to take extra precautions.
Before receiving the contrast, tell your doctor if you have kidney problems. You may not be able to get IV contrast if this is the case.
