#

Procedure

Definition

Key Indications

Key Contraindications

Rationale / Key Point

1

HSG

Fluoroscopic study of the uterus & tubes using contrast

Infertility, recurrent pregnancy loss, tubal blockage, uterine anomalies

Pregnancy, PID, bleeding, contrast allergy

Evaluates uterine & tubal structure; slow injection prevents false blockage; sterility prevents infection

2

Pelvimetry

Measurement of the maternal pelvis

Cephalopelvic disproportion, large fetus, breech, prior trauma

Pregnancy (X-ray), US/MRI available

Determines if vaginal delivery is safe; CT/US is safer than X-ray

3

Amniography (Historical)

Contrast study of the amniotic sac

Placental localization, fetal position, and congenital anomalies

Infection, coagulopathy, pregnancy

Pre-US technique; visualized placenta & fetus, but high fetal risk

4

Pelvic Pneumography (Historical)

Gas into the peritoneal cavity to outline organs

Pelvic mass differentiation, ovarian vs intestinal pathology

Pregnancy, peritonitis, obstruction

Negative contrast for organ outline; replaced by US/CT

5

Vaginography

Contrast imaging of the vagina

Congenital anomalies, fistulas, trauma, tumors

Pregnancy, vaginitis, contrast allergy

Detects structural abnormalities; gentle technique prevents trauma

6

Placentography (Obsolete)

IV contrast to visualize the placenta

Placenta previa, abruption

Pregnancy

Visualized placenta pre-US; replaced due to fetal radiation risk

7

Fetography (Historical)

X-ray imaging of the fetus

Fetal age, anomalies, multiple gestation, presentation

Viable pregnancy

Skeletal assessment pre-US; abandoned due to radiation

8

Prostatography

Contrast study of prostate & urethra

Prostate enlargement, urethral obstruction, trauma

Prostatitis, urethral injury, contrast allergy

Maps obstruction & urethral integrity; reduces trauma with careful technique

9

Cholecystography (Oral/IV)

Gallbladder imaging with contrast

Gallstones, cholecystitis, obstruction, and dysfunction

Vomiting, iodine allergy, pregnancy, liver failure

Visualizes stones & function; timing and diet optimize contrast uptake

10

GI Series

Barium/water-soluble imaging of the GI tract

Dysphagia, reflux, ulcers, obstruction, malrotation, tumors

Perforation (use water-soluble), allergy, pregnancy

Coats mucosa & lumen; fluoroscopy allows functional assessment

11

Hypotonic Duodenography

Duodenal study after glucagon relaxation

Duodenal tumors, early pancreatitis, diverticula, partial obstruction, SMA syndrome

Glucagon allergy, severe ileus, diabetes

Glucagon relaxes the duodenum for better imaging; glucose monitoring in diabetics

12

Arthrography

Joint contrast study (sometimes with air)

Ligament/meniscal injuries, capsule abnormalities, chronic pain, prosthesis evaluation

Infection, contrast allergy, bleeding disorders

Highlights joint space, capsule, ligaments; multiple positions reveal pathology

13

Bronchography (Historical)

Bronchiectasis, chronic infections, and congenital anomalies

Severe respiratory disease, bronchospasm, contrast allergy

Shows airway anatomy; replaced by CT due to safety/resolution

14

Myelography

Spinal canal study with intrathecal contrast

Disc herniation, stenosis, tumors, arachnoiditis, CSF leak

Infection, raised ICP, contrast allergy, coagulopathy

Visualizes spinal canal & nerve roots; Trendelenburg & positioning optimize contrast flow

15

Nasolacrimal obstruction, epiphora, congenital anomalies, trauma

Acute infection, contrast allergy

Outlines tear ducts; gentle technique prevents trauma and infection
