2  Pelvic CT.  Indications.  Contraindications.  Pelvic CT protocols. - Truma protocol. - Pathology protocol.  Patient after care.

3 It is an imaging method that uses x-rays to create cross-sectional pictures of the organs inside the pelvis (bladder, prostate, lymph nodes and pelvic bones).

4  Pelvic truma or fracture.  Hematuria or suspected renal calculus.  Hematoma.  Suspected hemorrhage.  Hip osteonecrosis.  Ischemic bowel.  Pelvic inflammatory or infection disease(abscess/colitis).  Pelvic vein thrombosis.  Congenital abnormalities e.g. CHD.  Tumors, suspected or known (Lymphadenopathy/Primary or metastatic malignancies) CHD Ewing sarcoma osteosarcoma of the ilium

5 There are no absolute contraindications to pelvic CT examinations, the relative benefits should be outweigh the exposure risk. Check the following conditions : –ALLERGIES, ASTHMA, DIABETIES, KIDNEY DISEASE Ask if a patient is PREGNANT. Ask about prior reaction to contrast.

7 Truma protocol (C-) E.g. to rule out fractures or history of truma. Patient preparation : No need for pt. preparation since he comes directly from the ER. - Pt. should be stable (vital sings). - On stretcher. -No need to be NPO except if a sedation is needed ( NPO for 3-4 hrs). Patient position : -Supine. -Feet first in gantry. -Hands above the head.

8 -The vertical center is in the middle of the pelvis. -The axial center is in the iliac crest.

9 Type of recons. DFOVSFOVmAK.VEnd locat. Start locat. SpaceThicknessType of scan Standard 30 – 50 cm The size of the Pt. M,L The size of the Pt. Auto mA Mid of thigh. L Helical Standard window Bone window 2 nd reconstruction Bone window fractures.

10 - When the scan is end we can have 2D reformats (coronal, sagittal ) and 3D pelvis.

11 pathology protocol (C+) E.g. Ca ovarian, mass or swelling Patient preparation : - 60 ml castor oil the night before the procedure. - NPO from mid night. - The patient should be in department 2hrs before start the procedure. - check that pt. not allergic or asthmatic. - Check pt. renal function test ; for inpatient 1 week outpatient (diabetic) 3 months outpatient (non-diabetic) 6 months - Pt. is given the oral contrast gastrografin or telebrix 3% (30 ml in 1000 ml of water ), one cup every 10 min.

17 (C) Coronal CT reformat shows fluid-filled diverticulum (arrow). (D) Sagittal CT reformat shows a diverticulum descending from the inferior border of the small bowel (arrow). CT axial images with oral and intravenous contrast. A fluid filled diverticulum.

18 -The site of contrast injection will be bandaged. -The technologist will continue to watch the patient for possible adverse contrast reactions. -Pt. can eat or drink as normal. - If the Pt. inject with contrast, he/she should drink plenty of liquid to help flush it out from there system.
