Abstract:Objective To investigate the differences of MRI imaging in lung cancer (chest) and liver cancer (abdomen) by patient
patient-initiated breath-holds and radiographer-instructed breath-holds. Methods A total of 64 patients suspected lung cancer (58
male patients and 6 female patients) were included, T1WI-DIXON and T2WI-STIR sequences were used for MRI scanning, and
each patient was collected by different breath-holding methods. A total of 103 patients (75 males and 28 females) with suspected
liver cancer were selected for MRI scanning using T1-DIXON and T2WI-DIXON sequences, and each patient was collected by
different breath-holds methods. The obtained MRI images were evaluated and graded by 3 radiologists. Results In chest examination
and abdominal examination, there was no significant difference in overall image quality or respiratory motion artifacts in patients
with autonomous breath-holds compared with radiographic-instructed breath-holds, which was used clinically for longer periods.
Conclusion Patient-initiated breath-holds become an alternative of traditional radiographers-instructed breath-holds and can make
contribution to improve patients comfort in MRI.
