Abstract

Lumbar Spinal Injury can cause various pathological abnormalities, such as compression fractures, burst fractures, and compression of neurological structures that may lead to permanent neurological deficits. Magnetic Resonance Imaging (MRI) is one of the imaging modalities frequently used in Spinal Injury cases because it provides detailed visualization of soft tissues and the spinal cord. Several studies have reported the use of T1-weighted (T1W), T2-weighted (T2W), Short Tau Inversion Recovery (STIR), and Fast Field Echo (FFE) sequences in MRI examinations of spinal injuries. However, the MRI protocol at the Radiology Department of West Nusa Tenggara Provincial Hospital utilizes T1W-TSE, T2W TSE, T2W-SPIR, and myelography sequences without the routine use of the FFE sequence. This study aimed to analyze the MRI examination procedure of the Lumbosacral Vertebrae in Spinal Injury cases and to determine the reasons for not routinely using the FFE sequence. This study employed a qualitative descriptive method with a case study approach. Data were collected through observation, structured interviews, and documentation. The respondents consisted of three radiographers and three radiologists involved in MRI examinations. The results showed that the FFE sequence has not been included as a routine sequence in MRI examinations of Lumbosacral Spinal Injury cases at West Nusa Tenggara Provincial Hospital, but is used as an additional sequence based on specific clinical indications. This sequence is beneficial for detecting hemorrhage due to its sensitivity to susceptibility effects; however, it is not routinely applied because most cases examined do not present indications of hemorrhage, and the sequence may produce artifacts that can reduce image quality.

Abstract

The aim of this research is to determine the role of the Diffusion Weighted Imaging (DWI) sequence in Soft Tissue MRI examinations of the neck in cases of nasopharyngeal cancer and to determine the advantages of using the Diffusion Weighted Imaging (DWI) sequence in MRI Soft Tissue examinations of the neck in cases of nasopharyngeal cancer. The research method used was a descriptive qualitative research method with a literature study method. The results of the literature review research showed: 1) Nasopharyngeal cancer, especially squamous cell carcinoma, can be treated with radiation therapy where treatment failure is still a serious problem, especially in advanced cases. DWI and ADC are imaging methods that utilize the movement of water inside. DWI provides additional information regarding response to treatment in hard-to-reach cases of nasopharyngeal cancer. plays an important role in detection, evaluation of response to treatment, and early monitoring of chemoradiotherapy therapy. DWI also provides information that helps distinguish between tissue experiencing post-RTH fibrosis and areas that may contain active cancer cells. DWI and ADC are also useful in tumor staging, delineation of target volumes, and detection of tumor recurrence. Elevated ADC may be indicative of a favorable response to therapy, whereas low pretreatment ADC values ​​may predict a favorable response. In the diagnosis of nasopharyngeal cancer, DWI and ADC also help differentiate squamous cell carcinoma subtypes, predict response to chemoradiation therapy, and determine the appropriate time for alternative treatment regimens. 2) DWI and ADC provide advantages in the diagnosis and monitoring of nasopharyngeal cancer. DWI can image restrictions on water diffusion within tissue, helping to detect areas of high cell density associated with tumors. Its advantages include sensitivity to microenvironmental changes and the ability to early identify recurrence or secondary cancer post-radiation therapy.
