Background: The MRI knee joint examination procedure for clinical ACL rupture in the Radiology Installation of Sidoarjo Regional Hospital often adds a T2 Mapping MR Cartigram sequence. T2 mapping MR Cartigram is a special sequence for detecting damage to the collagen component of the cartilage matrix using a quantitative approach method by producing a color map. The aim of this research is to determine the procedure, reasons for use, and diagnostic information resulting from the T2 mapping MR Cartigram sequence. Method: This type of research is qualitative research with a case study approach. The research was conducted in March-June 2022 at the Radiology Installation of Sidoarjo Regional Hospital. Research subjects included three patients, three radiographers, one radiologist, and one sending doctor. Data was collected by means of observation, interviews and documentation and then analyzed using an interactive model system method which would be processed in the form of transcripts, then identified, reduced and categorized the data and made open coding so that conclusions could be drawn. Results: The results of the study show that the clinical MRI knee joint examination procedure for ACL rupture at Sidoarjo District Hospital includes patient preparation, equipment preparation, examination techniques and routine sequences used such as PD Fatsat, T2, T1, STIR, T2*GRE, PD 3D Cube, and additional T2 Mapping MR Cartiram sequence. The use of the T2 mapping MR Cartigram sequence aims to determine the effect of ACL rupture on cartilage damage quantitatively and objectively by placing an ROI in the cartilage area so that it can provide diagnostic information including early detection of cartilage damage, increased water content, and cartilage degenerative processes. The results of the interpretation of the analysis carried out by the Sidoarjo Regional Hospital Radiologist were only subjective, namely looking at the resulting color map to see whether it looked even and homogeneous. Conclusion: Basically, existing saturation measurements are not always the same, they will depend on the patient's diagnosis for which the action will be taken. This saturation measurement uses the AVOXimeter 1000E. no less important in the continuity of actions in the cath lab room.

The aim of this research is to determine the Lumbar MRI examination procedure in LBP cases at the Bogor City Regional Hospital, namely STIR and Myelo Radial, the aim of which is to clearly see abnor malities in the intervertebral discs and stenosis in the cerebral spinal cord. This type of research uses descriptive qualitative methods with a case study approach. Data collection methods are carried out through observation, interviews and documentation. Then data analysis was carried out using open coding charts, so that conclusions could be drawn. The results of this study show that the Lumbar MRI examination procedure in cases of Low Back Pain (LBP) at the Bogor City Regional Hospital does not require special preparation, the patient comes to radiology for screening (installation of a pacemaker). The patient removes clothing and metal objects. Before the examination, the patient is asked to urinate first, the patient's position is supine (feet first), iso center 5 cm superior to the ASIS. Then it is briefly explained that during the examination you are not allowed to move and the duration of the examination is 15 minutes and the role of the sagittal STIR sequence and Myelo Radial. The role of the sagittal STIR sequence and myelo radial to suppress fat in the cerebral spinal fluid, conus medullaris and myelum in the spinal cord and to see masses Lesions and stenosis caused by narrowing of the bulging in the intervertebral disks are clear enough to provide a Lumbar MRI image for cases of Low Back Pain (LBP).
 

Herniated nucleus pulposus (HNP) is the leading cause of back pain in old age, occurring as a result of tearing of the fibrous annulus and the nucleus pulposus exiting through the tear. To optimize pathology, fat suppression techniques are needed to suppress fat and fluid. Fat Suppression techniques include Dixon and SPAIR. The use of Dixon is relatively longer but can produce four images at once, while SPIR has the advantage of being more resistant to inhomogeneous magnetic fields. The purpose of this study was to determine the difference between T2WI SPIR and T2WI diagnostic image information Dixon Sagital Cut Lumbar MRI with Hernia Nucleus Pulposus (HNP) cases as well as find out which one is better between the two techniques. The type of research used is quantitative research with an experimental approach that uses prospective data aimed at determining the difference in diagnostic image information T2WI SPIR and T2WI Dixon MRI examination of Sagital Cuts. The study population is patients who perform Lumbar MRI examinations with HNP cases at the Radiology Installation of NTB Provincial Hospital for the period May-July 2023. This study applied total sampling, using a research sample of 17 patients. The results showed a difference in image information between the T2WI SPIR and T2WI Dixon sequences on Lumbar MRI examination of Sagital Cut with a p-velue value smaller than ? (<0.05), namely in the anatomy of the Spinal Cord with a p-value (0.021), and the anatomy of the Corpus Vertebraewith value p-value (0.001). The T2 Spir sequence is more optimal in showing anatomical information on the Sagittal Cut lumbar MRI examination compared to the T2 Dixon sequence.  due to the more homogeneous emphasis of fat on the anatomy of the Spinal Cord and Corpus Vertebrae
