Some modern scanners have larger bores (up to 70 cm) and scan times are shorter. A 1.5 T wide short bore scanner increases the examination success rate in patients with claustrophobia and substantially reduces the need for anesthesia-assisted MRI examinations even when claustrophobia is severe.

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.
Anesthesia is used to control pain by using medicines that reversibly block nerve conduction near the site of administration, therefore, generating a loss of sensation at the area administered. Close monitoring by the anesthesia provider will sometimes be provided, to help keep the patient comfortable during a medical procedure, along with ...
An MRI scan entails lying still for some time in a narrow tube. In a study involving claustrophobia and MRI, it was reported that 13% of patients experienced a panic attack during the procedure. The procedure has been linked not only to the triggering of 'preexisting' claustrophobia, but also to the onset of the condition in some people. [6]
Amnesia is desirable during surgery, so general anaesthesia procedures are designed to induce it for the duration of the operation. Sedatives such as benzodiazepines, which are commonly used for anxiety disorders, can reduce the encoding of new memories, particularly in high doses (for example, prior to surgery in order for a person not to recall the surgery).

These are usually retrospectively-gated and have intrinsically high contrast in cardiac imaging due to the relatively high T2:T1 ratio of blood compared to myocardium. Images are typically planned sequentially to achieve the standard cardiac planes used for assessment.
Procedural sedation and analgesia (PSA) is a technique in which a sedating/dissociative medication is given, usually along with an analgesic medication, in order to perform non-surgical procedures on a patient. The overall goal is to induce a decreased level of consciousness while maintaining the patient's ability to breathe on their own.
Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane , diethyl ether , propofol , etomidate , ketamine , pentobarbital , lorazepam and midazolam .
