   Word Origin late Middle English (as a verb in scan (sense 3 of the verb)): from Latin scandere ‘climb’ (in late Latin ‘scan (verses)’), by analogy with the raising and lowering of one's foot when marking rhythm. From ‘analyse (metre)’ arose the senses ‘estimate the correctness of’ and ‘examine minutely’, which led to ‘look at searchingly’ (late 18th century).

   2 days ago · A-scan ultrasound biometry, commonly referred to as an A-scan (short for Amplitude scan ), uses an ultrasound instrument for diagnostic testing. [ 1] A-scan biometry measures the axial length (AL) of the eye prior to cataract surgery in order to assess the refractive power of the intraocular lens that will be implanted.

   What is a a-scan used for?

   • The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. Briefly, the total refractive power of the emmetropic eye is approximately 60.

   What is MRI scanning based on?

   • Fig 1 MRI scanning is based on the excitation and relaxation of protons. Magnetic resonance imaging can produce highly sophisticated and highly detailed images of the human body. Generally speaking, MRI scanning is excellent for visualising soft tissue – and so it is often used in the detection of tumours, strokes and bleeds.

   What is a quantitative a-scan?

   • The other major use of the A-scan is to determine the size and ultrasound characteristics of masses in the eye, in order to determine the type of mass. This is often termed quantitative A-scan. [citation needed] Instruments used in this type of test require direct contact with the cornea, however a non-contact instrument has been reported.
