Isotope Notation

error

"The lung shunt fraction = (total lung counts) / (total lung counts + total liver counts). It is usually calculated using ^99mTc-MAA. Guidelines suggest a maximum per treatment dose of 30Gy and a maximum total dose of 50Gy."

Line 2:133 · Write the isotope as symbol-mass, e.g. F-18, not '99mTc'.

Units

error

"The lung shunt fraction = (total lung counts) / (total lung counts + total liver counts). It is usually calculated using ^99mTc-MAA. Guidelines suggest a maximum per treatment dose of 30Gy and a maximum total dose of 50Gy."

Line 2:133 · Put a space between the number and the unit in '99mTc'.

Hybrid Imaging Slash

error

"Compared to SPECT/CT, planar scintigraphy may overestimate lung dose especially in those with left-sided tumours, high LSF and high BMI leading to unnecessary dose reduction ¹."

Line 3:16 · Hybrid imaging takes a hyphen, not a slash: 'SPECT/CT'.
