Characterizing and quantifying low-value diagnostic imaging internationally: a scoping review

BMC Medical Imaging

Table 13 Overview of low-value imaging in Neck and ear, nose, and throat imaging

Type of imaging	Reason for examination	Outcome	Suggested practice by included study/studies	References
Post-op thyroid US	Thyroid cancer	2% relevant findings		[270, 271]
Radioactive iodine scanning	Thyroid cancer	Does not find more than other type of imaging	Use fine needle aspiration diagnostics	[274]
Follow-up thyroid US	After lobectomy	1.5% relevant findings		[275]
Pre-op Tc-99 m-sestamibi	Secondary hyperparathyroidism	Nodules are found during surgery		[276]
Sinus CT/XR	Acute rhinosinusitis	Does not change patient management		[277]
Face CT/XR	Facial fracture	Does not change patient management		[278,279,280,281,282]
Face CT	Zygomatic arch/ mandibular fracture	Using other examinations reduce radiation dose with similar quality	Face US often combined with face XR	[281]
Face MRI	Juvenile ossifying fibroma	Low diagnostic accuracy	Face CT is of better quality	[283]
Pre-op templar bones CT	Cochlear implants	14% relevant findings		[284]
Templar bones CT	Chronic Eustachian tube dysfunction	Does not change patient management		[285]
