Assessment of Technetium-99m Labeled Macroaggregated Albumin Rhinoscintigraphy for the Measurement of Nasal Mucociliary Transport Rate: Intratest, Interobserver, and Intraobserver Reproducibility

Table 1

Nasal mucociliary transport rates measured for intratest, interobserver, and intraobserver reproducibility and statistical comparison.

Type of reliability	NMTR (mm/min)		𝑃 value
	Mean ± SD	Range
Intratest (𝑛=22)
1st scan	8±3.4	2–12.4	0.338
2nd scan	7.9±3.3	1.9–13.2
Interobserver (𝑛=35)
Observer 1	6.8±3.3	1.5–12.4	0.211
Observer 2	7.2±3.7	1.4–13.5
Intraobserver (𝑛=35)
1st measurement	6.8±3.3	1.5–12.4	0.421
2nd measurement	7±3.6	0.8–12.1
