[1] [2] The presence of the steeple sign supports a diagnosis of croup, usually caused by paramyxoviruses. [3] It can also be defined as the replacement of the usual squared-shoulder appearance of the subglottic area by cone-shaped narrowing just distal to the vocal cords. This is called the steeple or pencil-point sign.
Croup is typically diagnosed based on signs and symptoms after potentially more severe causes, such as epiglottitis or an airway foreign body, have been ruled out. [4] Further investigations, such as blood tests, X-rays and cultures, are usually not needed. [4] Many cases of croup are preventable by immunization for influenza and diphtheria. [5]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
It is necessary for most users of the CPT code (principally providers of services) to pay license fees for access to the code. [19] In the past, AMA offered a limited search of the CPT manual for personal, non-commercial use on its web site. [20] CPT codes can be looked up on the AAPC (American Academy of Professional Coders) website. [21]
Megavolt X-ray (or photon) therapy, which delivered a beam of 25 MeV X-ray photons. The X-ray photons are produced by colliding a high current, narrow beam of electrons with a tungsten target. The X-rays are then passed through a flattening filter, and then measured using an X-ray ion chamber. The flattening filter resembles an inverted ice ...

Intravenous digital subtraction angiography (IV-DSA) is a form of angiography which was first developed in the late 1970s.. IV-DSA is a computer technique that compares an X-ray image of a region of the body before and after radiopaque iodine based dye has been injected intravenously into the body.
These include mother-baby and SpyGlass cholangioscopes (to help in diagnosis by directly visualizing the duct as opposed to only obtaining X-ray images [13] [14] [15]) as well as balloon enteroscopes (e.g. in patients that have previously undergone digestive system surgery with post-Whipple or Roux-en-Y surgical anatomy).
