Pneumothorax : A pneumothorax is an abnormal collection
of air or gas in the pleural space that separates the lung from the chest wall
Pnuemoperitoneum : Pneumoperitoneum is the presence of air
or gas in the abdominal (peritoneal) cavity. It is often seen on X-ray, but small amounts are often missed, and CT is needed...

Contrast study Oral contrast:
Baruim swallow :A barium swallow (or esophagography) is a medical imaging procedure used to examine the upper GI (gastrointestinal) tract
Baruim meal :A barium meal, also known as an upper gastrointestinal series is a procedure in which radiographs of the esophagus, stomach and duodenum
Baruim enema :A barium enema, or lower gastrointestinal (GI) examination.
Contrast is radio-opaque
I V Contrast :
Angiogram Angiography or arteriography is
a medical imaging technique used to visualize the inside, or lumen, of blood vessels .

Ultrasound An ultrasound machine creates images that
allow various organs in the body to be examined.
The machine sends out high-frequency sound waves, which reflect off body structures.
A computer receives these reflected waves and uses them to create a picture. Unlike with an x-ray or CT scan, there is no ionizing radiation exposure with this test.

-Xray computed tomography, also computed tomography (CT scan), computed axial tomography (CAT scan) or computer assisted tomography is a medical imaging procedure that uses computer-processed X-rays to produce tomographic images or 'slices' of specific areas of the body.
These cross-sectional images are used for diagnostic and therapeutic purposes in various medical disciplines.

MRI can create more detailed images of the human body than are possible with X-rays.

An MRI scanner is a device in which the patient lies within a large, powerful magnet where the magnetic field is used to align the magnetization of some atomic nuclei in the body,
Radiofrequency magnetic fields are applied to systematically alter the alignment of this magnetization.This causes the nuclei to produce a rotating magnetic field detectable by the scanner—and this information is recorded to construct an image .
