Arthrograms
1. Commonly Examined Synovial Joints:
- Knee
- Shoulder
2. Contraindications for an Arthrogram:
- Sensitivity to iodine
- Sensitivity to local anesthetics
3. Indication for Knee Arthrogram:
- A possible Baker's cyst suggests the need for an arthrogram procedure for the knee.
4. Types of Contrast Media for Knee Arthrogram:
- Iodinated water-soluble
- Carbon dioxide, oxygen, or room air
5. Purpose of Flexing the Knee:
- To provide a thin, even coating of positive contrast media over the soft tissues of the knee joint.
6. Number of Exposures for Knee Arthrograms:
- 9 exposures are typically made.
7. Leg Rotation for Horizontal Beam Knee Arthrograms:
- The leg is rotated 20 degrees between each exposure.
Shoulder Arthrogram
1. Rotator Cuff Definition:
, - The term rotator cuff refers to the conjoined tendons of the four major shoulder muscles.
2. Needle Type for Shoulder Arthrogram:
- 2 3/4 - 3 1/2 inch spinal needle is most often used to introduce contrast media.
3. Scout Projections for Shoulder Arthrogram:
- AP internal rotation
- AP external rotation
4. Postinjection Projections for Shoulder Arthrogram:
- Glenoid fossa projection (Grashey method)
- Transaxillary (inferosuperior axial) projection
- Intertubercular (bicipital) groove projection (Fisk method)
Endoscopic Retrograde Cholangiopancreatography (ERCP)
1. Instillation of Contrast Medium into Biliary Ducts:
- Through a special catheter introduced through the duodenoscope.
2. Physician Performing ERCP:
- Typically performed by a gastroenterologist.
3. Common Clinical Reason for T-tube Cholangiogram:
- To detect postoperatively any residual stones in the biliary ducts that may have gone undetected
during the cholecystectomy.
Hysterosalpingogram (HSG)
1. Divisions of the Uterus:
- Fundus
- Corpus (Body)
