2. Barium swallow is a
dedicated test of
the pharynx, oesophagus
and GE Junction.

3.  Dysphagia and obstruction.
 Pain during swallowing.
 Assessment of mediastinal masses.
 Assessment of left atrial enlargement.
 Pre-op assessment of carcinoma bronchus and oesophagus.
 Motility disorders of oesophagus, E.g.: Achalasia and diffuse
oesophageal spasm, scleroderma.
 Assessment of site of perforation.
 Zenker's diverticulum and cricoid webs.

4.  Tracheo-oesophageal fistula.
 Perforation.
 Leakage of barium from an unsuspected perforation-granuloma
formation.
 Aspiration.

5. Nil orally for 6 h prior to the examination.
The patient is advised not to smoke on the day of the
examination, as it increases gastric motility.
It should be ensured that there are no contraindications to
the Preliminary film Technique or pharmacological agents
used.

6. Barium meal is the
radiological study of
stomach and duodenum.
It is done by oral
administration of contrast
media (Barium sulphate).

7. Dyspepsia
 Weight loss
Upper abdominal mass
Gastrointestinal haemorrhage (or unexplained iron-
deficiency anaemia)
 Partial obstruction
Assessment of site of perforation - it is essential that a
water- soluble contrast medium, e.g. Gastrografin or
LOCM, is used.

8. Complete large bowel obstruction.
Nil orally for 6 h prior to the examination.
The patient is advised not to smoke on the day of the
examination, as it increases gastric motility.
It should be ensured that there are no contraindications
to the pharmacological agents used.

9. It is the radiographic examination of
the small bowel up to ileocecal
junction by oral administration of
contrast media. It is so-called
because it is performed following a
barium meal examination of the
oesophagus, stomach and
duodenum.

10.  Patients who have low suspicion of small bowel disease
abdominal pain and diarrhoea.
 Patients with suspected complete (or) near complete small bowel
obstruction.
 Patients who are suspected of suffering from Crohn's disease.
 Patients who refuse placement of nasogastric tube/failed
intubation.
 Elderly patients with suspected jejunal diverticulosis who present
with malabsorption.

11. Colonic obstruction.
Suspected perforation.
Paralytic Ileus.

12. The colon should be cleaned by the administration of
a suitable purgative. (Purgative should be avoided in
patients with suspected obstruction, acute
exacerbation of Crohn's disease or an Ileostomy).
A low roughage diet and a high fluid intake is also
maintained for 48 hours prior to the investigation
No food or fluid should be taken for 12 hours before
the investigation. If the patient is taking tranquilizers,
antispasmodics and codeine, they should be stopped
for 24-48 hours before the examination.

13. It is the radiographic
study of the large bowel
by administration of the
contrast medium through
the rectum.

On the day of examination
A tap water cleansing enema of 1500 ml

17. It is the radiographic
examination of urinary
tract including renal
parenchyma, calyces
and pelvis after
intravenous injection of
contrast media.

18. 1. Screening of the entire urinary tract especially in cases of haematuria or pyuria.
2. Diseases of the renal collecting system and renal pelvis
3. Differentiation of function of both kidneys.
4. Abnormalities of the ureter.
5. Obstructive uropathy- IVU is the gold standard.
6. TB of the urinary tract
7. Calculus disease.
8. Potential Renal Donors.
9. Prior to endo-urological procedures and surgery of urinary tract.
10. Suspected renal injury.
11. Renal colic or flank pain.

19. 1. VATER anomalies: These patients have vertebral, anal, tracheo oesophageal, and
renal anomalies. Renal anomalies are seen in about 90% of patients.
2. Malformation of urinary tract, e.g., polycystic disease, PUJ obstruction etc.
3. Neurological disorders affecting urinary tract.
4. Malformation of genitalia like bilateral cryptorchidism, III degree hypospadias,
family history of urinary tract anomalies, urinary tract infection.
5. Enuresis in the presence of bacteriuria,abnormal urinary sediment, adolescents,
diurnal/nocturnal incontinence and history of recurrent urinary tract infection.
6. In girls with constant or intermittent dampness which suggests an ectopically
inserted ureter, IVU is mandatory.
7. Anorectal anomalies.

20. 1. Iodine sensitivity.
2. Pregnancy.
3. Severe history of anaphylaxis previously carries 30% risk of similar reaction on a
subsequent occasion. The risk is lower with low osmolar contrast media.
4. Raised serum creatinine levels

21. • overnight fasting for 5 hours prior to the date of examination; a laxative
may not be necessary for bowel preparation as it does not improve
image quality
• on the day of the procedure take a scout/pilot film to check patient
preparation and also to look for radiopaque calculi
• check serum creatinine level to be within the normal range (as per
hospital guidelines)
• take a history of the patient for any known drug allergies followed by
written informed consent for the procedure
• emergency medications and emergency equipment must always be
available in case the patient has a reaction to contrast

22.  Voiding cystourethrography also
known as a micturating
(MCU), is a fluoroscopic study of
the lower urinary tract in which
introduced into the bladder via a

23. 1.UTI-Usually done after some weeks after acute stage or may be done under
antibiotic coverage.
2.Voiding difficulties like dysuria, thin stream, dribbling, frequency, urgency.
3.Vesico ureteric reflux.
4.Other congenital anomalies : Meningomyelocele, Sacral agenesis,
5.Rectal anomalies.

examination.

37. It is a fluroscopic
procedure in which the
contrast is injected into
the uterus to study the
uterine cavity and
fallopian tubes.
