Adjectival Hyphens

error

"The perfusion lung scan involves injecting Tc-99m MAA intravenously in the supine position. The MAA particles are just small enough to get lodged in the pre-capillary arterioles. A high resolution, large field of view gamma camera is used to image the lungs."

Line 11:164 · 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: 'pre-capillary'.

"Interpretive criteria developed from the PIOPED, PIOPED II, or PISAPED trials can be used to determine the probability of a pulmonary embolism on a V/Q scan. For the diagnosis of PE, a V/Q scan has a reported sensitivity of 77.4% and specificity of 97.7% when compared to CT pulmonary angiography (CTPA) or digital subtraction angiography (DSA) ³."

"Indications"

Line 2:1 · "Indications" should be H2, not H1.

Inline EG

suggestion

"diagnosis of suspected pulmonary embolism, particularly in patients with a contraindication to CTPA (e.g. iodine allergy)"

Line 4:115 · Consider replacing a bracketed e.g. with an inline e.g. after a comma.

Oxford Comma

suggestion

"The ventilation scan is performed using radio-isotope labelled aerosols like technetium-99m DTPA delivered to the patient through a non-rebreathing mask, with the patient supine. The micro-aerosol particles are small enough to reach the distal tracheobronchial tree and reflect regional ventilation ¹.The patient is then imaged in the upright position in three phases: initial breath, equilibrium and washout."

Line 10:418 · Use the Oxford comma in 'breath, equilibrium and washout'.
