Abstract

Examinations performed on MRI of cervical vertebrae take a long time and cause patients to feel uncomfortable during the examination. FSE is a technique that can be used to produce fast examination times. Patient discomfort can also cause movement during the examination, which can cause artifacts in the resulting images. These movements can be minimized with the PROPELLER technique. This study is quantitative using an experimental method with a sample size of 15 volunteers who were each scanned with T2 FSE and T2 PROPELLER sequences. This study was conducted using a questionnaire in which each image produced was evaluated by 2 radiology specialist observers using the visual grading analysis (VGA) method to assess each anatomy of the corpus vertebrae, intervertebrae disc, spinal cord, CSF, intraforamen structure, nerve root and artifacts. The statistical results showed that the image quality of T2 FSE and T2 PROPELLER sequences had ap value of 0.000 (p<0.05). The sequence has a difference, namely T2 PROPELLER produces more detailed image quality on anatomy and pathology, and can reduce the occurrence of artifacts due to movement in the cervical area, and T2 FSE produces less informative image quality due to artifacts. In addition, there are differences in MRI scanning time of cervical vertebrae T2 FSE sequences which are faster than T2 PROPELLER and T2 PROPELLER is good at reducing artifacts.

Abstract

MRCP is a non-invasive imaging method used to visualize the biliary system and detect abnormalities in the bile ducts or gall bladder. In taking images, there are two techniques, namely the mouth breath hold (MBH) technique and the trigger technique, where the MBH technique is carried out by the radiographer giving instructions directly related to the patient's respiratory movements, while the trigger technique uses respiratory gating to detect breathing patterns and minimize image blur due to organ movement. At Department of Radiology SMC Telogorejo Semarang both techniques are used in MRCP examinations by looking at the condition of each patient. So the author is interested in comparing the results of anatomical information from the two techniques. Methods: This research uses a quantitative design with an experimental approach. Data was collected from 10 patients who underwent MRCP examinations at the Department of Radiology SMC Telogorejo Semarang in August–September 2024. The scanning procedure was carried out using a T2 HASTE coronal section sequence twice for each patient using the MBH and trigger technique. Anatomical information was assessed by means of visual grading analysis by 3 radiologists on the structure of the cystic duct, intra-hepatic duct, common hepatic duct, common bile duct, pancreatic duct, and gallbladder (gallbladder) using a questionnaire with a scale (1–4). Then the data was analyzed using SPSS to determine whether there were differences in image information from the two techniques using the Wilcoxon difference test. This research has passed the ethical test number: KEPK/UMP/170/I2025. Results: Based on the results of the Wilcoxon test, both for the entire anatomy and for each anatomy, it shows a p-value < 0.05. This indicates that there are significant differences in the anatomical information produced by the two techniques. Based on the mean rank value, the most optimal technique for displaying anatomical information is MBH. This advantage is due to its ability to reduce movement artifacts through the breath-hold method, resulting in clearer and more detailed anatomical images compared to the trigger technique. The MBH technique is more effective in improving MRCP anatomical information, especially in patients with respiratory instability. It is hoped that these results can be a reference in determining the optimal method for MRCP examination.
