    Study Notes

    Special Radiological Procedures

    • Complications of hysterosalpingography (contrast medium): Increased pain from smooth muscle contraction, allergic phenomena (contrast entering circulation), significant bleeding, or contrast medium intravasation into the venous system.

    • MRI sequences for reproductive system: T2-weighted images, dynamic contrast-enhanced MR images, diffusion-weighted images, and apparent diffusion coefficient (ADC) mapping.

    • Retrograde pyeloureterography complications (except): Pyelosinus extravasation, pain and fever, infection, and perforation or damage to the ureter or renal pelvis.

    • Percutaneous nephrolithotomy equipment (except): US machine, puncturing needle (18G), track dilating equipment, and pump injector.

    • Imaging modality for gynecological malignancy staging (acute pelvic emergencies): MRI and B-mode ultrasound. Also CT

    • Retrograde pyeloureterography contraindications: Acute urinary tract infection, chronic kidney disease, urinary stones, prostate enlargement, or ureteral fistula.

    • Percutaneous antegrade pyelography & nephrostomy purpose: Removal of kidney stones, treatment of urinary tract infections, induction of renal tract obstruction, introduction of a drainage catheter into kidney collecting system.

    • CT staging in gynecological malignancy typically performed with: IV contrast and oral contrast.

    • Postoperative procedures best performed after delay: Allow patient to recover, blood clot resolves, and infected systems drain.

    • Retrograde pyelography equipment: Fluoroscopy. Also CT, MRI, US and angiography.

    • Percutaneous antegrade pyelography/nephrostomy prep: Fasting for 4 hours, empty stomach; drinking fluids, and a clear indication for antibiotic therapy are crucial preparations. Avoid gastric being full prior to procedures.

    • Varicocele suspicion during scrotal ultrasound: Valsalva maneuver, deep breathing, coughing or jumping jacks are techniques to examine potential varicocele.

    • Percutaneous nephrostomy contraindications: Renal tract obstruction, pyonephrosis, uncontrolled bleeding, diathesis, prior to percutaneous nephrolithotomy, or ureteric/bladder fistulae.

    • Cyst puncture in percutaneous renal cyst puncture and biopsy: Removal or cyst wall, contrast medium injection into cyst, aspiration of cyst contents, placement of drainage tube into the cyst. Often placement of a stent is done as well.

    • Imaging for percutaneous renal cyst puncture and biopsy: Ultrasound and CT are commonly used imaging modalities to guide needle insertion. Alternatively, X-ray and MRI are possible, along with Fluoroscopy and PET, and SPECT and MRA.

    • MRI of reproductive system sequences for ovarian assessment: Axial or sagittal T1-weighted spin echo, axial or sagittal T2-weighted spin echo, and coronal T2-weighted fast spin echo scans.

    • MRI for scrotal hemorrhage assessment: High-resolution axial T1/T2 weighted spin echo scans are generally useful.

    • Ultrasound for scrotal imaging: 7.5-15-MHz linear transducers, 5-7-MHz endovaginal transducers, or 2-5-MHz curvilinear transducers are the typical transducers for ultrasound of the scrotum.

    • Percutaneous renal cyst puncture: Patients are typically in the supine or prone position during percutaneous procedures, depending on the type and location of the renal cyst.

    • Percutaneous nephrolithotomy: The procedure is typically done due to larger renal calculi or stones and other issues.

    • Hysterosalpingography equipment (not used): This exam does not use a biopsy needle.

    • Postoperative biliary anastomosis (e.g., liver transplant): 20 mL of contrast should be used when undergoing T-tube cholangiography in these cases.
