Functional Magnetic Resonance in the Evaluation of Oesophageal Motility Disorders

Table 1

Esophageal transit time and size in patients and controls measured by fMRI.

Groups	𝑁	Transit time (sec)	Oesophageal caliber (mm)
Controls	8	8.9±1.4	13.8±1.9
Motor alterations with constant peristalsis	4	8.3±1.5	16.5±1.3
Motor alterations with intermittent peristalsis	4	17.5±8.7^∧	16.8±7.5
Aperistalsis in non achalasic patients	6	30.8±22.9^∗	35.8±12.4^§§
Aperistalsis in achalasic patients	10	47.5±17.2^∗∗	34.3±15^§

^∧𝑃<0.06 versus controls.
* 𝑃<0.06 versus controls; 𝑃<0.06 versus constant peristalsis.
