McKeown procedure
The McKeown procedure ("tri-incisional esophagectomy") is a type of esophagectomy, that is similar in concept to an Ivor Lewis procedure, but it tends to be used for esophageal lesions that are higher in the esophagus.
Procedure
laparotomy

Fluoroscopic evaluation of esophagectomy
Fluoroscopic evaluation of esophagectomy is an important study, given the high rate of complication following esophagectomy (~10-20% rate of leak). Although the approach will differ slightly depending on the type of esophagectomy performed, the principles are similar.
Procedure
Preprocedural e...

Gastrointestinal nodular lymphoid hyperplasia
Gastrointestinal nodular lymphoid hyperplasia is a type of nodular lymphoid hyperplasia that can be found elsewhere in the body. It is formed out of gut-associated lymphoid tissue (GALT), and most often is a diagnostic dilemma for radiologists in the stomach and terminal ileum.

Single contrast enema
A single contrast enema is a method of imaging the colon with fluoroscopy and is similar in concept to the double contrast barium enema. "Single contrast" refers to imaging with a positive contrast medium, either barium or water-soluble contrast, without the addition of air or CO2.
Indications

Double contrast barium enema technique
Double contrast barium enema (DCBE) technique is a method of imaging the colon with fluoroscopy. "Double contrast" refers to imaging with the positive contrast of barium sulfate contrast medium (rarely water-soluble iodinated contrast) as well as with the negative contrast of gas (CO2 preferable...

CT fluoroscopy
Computed tomography (CT) fluoroscopy combines the conventional advantages of both CT and fluoroscopy and has an important role in image-guided interventions where real-time imaging is required.
Historically, fluoroscopy was the main image guidance tool for interventional radiology procedures. T...

Image reconstruction in CT fluoroscopy
Image reconstruction in CT fluoroscopy requires the computer to provide very fast reconstructions of images in order to provide immediate and accurate spatial and anatomical feedback during a procedure. This is achieved by:
use of a small reconstruction matrix – e.g. 256 x 256 (compared with co...

Radiation dose considerations in CT fluoroscopy
Consideration needs to be made to the radiation dose to both the patient and radiologist in CT fluoroscopy, given the relatively high and continuous radiation exposure involved.
Radiation exposure to the patient
The patient surface dosage may range between 2 and 10 mGy/sec, with exposure times...

Arthrogram (anesthetic)
An arthrogram injection is a procedure in which a solution is administered into a joint under imaging guidance. These procedures are more accurately named direct arthrogram injections, although they are routinely known as arthrograms. Fluoroscopy, ultrasound, and CT can be used for image guidanc...
