PERANAN PENGGUNAAN TEKNIK PARALLEL IMAGING GRAPPA PADA PASIEN MRI LUMBAL PADA PENDERITA HERNIA NUCLEUS PULPOSUS

Patients with clinical HNP often feel uncomfortable due to the length of time of examination, so a quick examination is required. Parallel imaging techniques can be used to speed up the inspection time, There is a parallel imaging technique that is generalized autocalibrating partially parallel acquisition (GRAPPA). This study aims to find out the role of grappa parallel imaging technique in lumbar MRI patients with Nucleus Pulposus Hernia diagnosis (HNP)This type of research is a type of descriptive research with a literary study approach. Journals are obtained by searching through search engines such as Google scholer and electronic database sites namely the American Journal of Roentgenology, Journal of Imejing Diagnostics. Selected journals based on the criteria of inclusion that have been determined and carried out the collection and presentation of data, until obtaining conclusionsLumbar MRI with HNP diagnosis has no specific preparation for the patient. Patients with clinical HNP often feel uncomfortable due to the length of time of examination. Grappa parallel imaging technique in mri examination lumbar HNP case has an important role, GRAPPA is very effective to accelerate the examination time while keeping the resulting SNR (received signal) remains good so as to produce optimal anatomical imagery
