Study Notes
Arthrography
- Main purpose of contrast arthrography: to evaluate joint problems
- Reduced necessity for radiographic contrast arthrography due to MRI and CT scans
- 'Arthro' refers to joints in arthrography
- Type of contrast media used in contrast arthrography: iodinated or gadolinium-based media
- Common gauge size for spinal needle: 22-25 gauge
- Procedure following skin preparation with Betadine: spinal puncture
- Approximate amount of contrast media injected: 10-15 mL
- Common position for spinal puncture: lateral decubitus or prone position
- Patient's head position during contrast injection: flexed to prevent contrast from entering cerebral ventricles
Myelography
- Main goal of myelography: to visualize the spinal canal and spinal cord
- Puncture site for myelography: usually in the L2-3 or L3-4 interspace
- Type of contrast used for myelography: water-soluble, non-ionic contrast media
- Contrast that can cause severe neurotoxic reactions if used for intrathecal injections: ionic contrast media
- Importance of locking the image intensifier during myelography: to minimize radiation exposure and ensure accurate imaging
Hysterosalpingography (HSG)
- Main goal of HSG: to evaluate the uterus and fallopian tubes
- Ideal time for scheduling HSG: during the follicular phase of the menstrual cycle
- Contraindications for HSG: pregnancy, active pelvic infection, and vaginal bleeding
- Non-contraindication for HSG: history of pelvic surgery
- Purpose of introducing contrast into the uterus during HSG: to visualize the uterine cavity and fallopian tubes
- Patient position during HSG: lithotomy position
- Therapeutic effect of HSG: can help clear blocked fallopian tubes and improve fertility
- Preparation before HSG procedure: patient should have an empty bladder and may take pain medication
