"most perfusion scans begin at the base of the pituitary fossa focusing on the basal ganglia and supra-ganglionic level with a shuttle range of around 10 cm."

Line 36:168 · Do not put full stops at the end of a list item.

"coverage of less than 8 cm will underestimate the ischaemic volume, while coverage of less than 4 cm will underestimate the core volume ¹."

Adjectival Hyphens

error

"Post-processing"

Line 80:5 · Only use medical adjectival hyphens where the letters at the end and start of the compound word are the same, e.g. post-transplant. In this case, don't use the hyphen: 'Post-processing'.

"Post-processing methods differ, depending on the vendor of the machine; however, the primary focus of the post-processing will be the measure of:"

Line 81:4 · Only use medical adjectival hyphens where the letters at the end and start of the compound word are the same, e.g. post-transplant. In this case, don't use the hyphen: 'Post-processing'.

Colons

warning

"NB: This article is intended to outline some general principles of protocol design. The specifics will vary depending on CT hardware and software, radiologists' and referrers' preference, institutional protocols, patient factors (e.g. allergy) and time constraints."

Line 2:6 · The first word after a colon should almost always be lowercase. In this case, it's not: ': This article'.

Acronyms

warning

"tube voltage is about 80 KV which is closer to the K-edge of iodine in order to reduce radiation dose and improve contrast enhancement ²"

Line 14:33 · 'KV' has no definition. Spell it out if it's unfamiliar to the audience.

Prefix Hyphens

warning

"most perfusion scans begin at the base of the pituitary fossa focusing on the basal ganglia and supra-ganglionic level with a shuttle range of around 10 cm."

Line 36:111 · A prefix takes a hyphen only to avoid a duplicate letter: 'supra-ganglionic'.

"perfusion scans focus on the pituitary fossa at the basal ganglia and supra-ganglionic level; however, patients with symptoms of cerebellar infarction will require an adjustment of the scan extent"

Line 75:78 · A prefix takes a hyphen only to avoid a duplicate letter: 'supra-ganglionic'.

Ranges

warning

"this exam requires an injection of contrast at a considerable rate (ranging from 6-8 mL/s); therefore, a large bore (at least 18 gauge) cannula is required"

Line 53:88 · Don't add words such as 'from' or 'between' to describe a range of numbers.
