Abstract

HNP (Hernia Nucleus Pulposus) terjadinya ketika nucleus pulposus keluar menonjol kemudian tonjolan tersebut menekan ke arah canalis spinalis melalui Annulus fibrosus yang robek, dan sering terjadi pada lumbal 4 – 2 lumbal 5 dan lumbar 5 – sacrum 1, MRI merupakan salah satu modalitas yang dapat menegakkan diagnose terhadap HNP, dengan menggunakan Teknik Fat Supression dalam penerapannya. Dixon dan Fat Saturation merupakan terknik fat suppression yang sering digunakan, akan tetapi memiliki kelebihan dan kekurangan dalam hasil gambaran maupun waktu akuisisi, maka penelitian ini membandingkan kedua Teknik tersebut dalam supressi lemak terhadap pasien HNP, dilihat dari hasil gambaran, homogenitas, dan hasil informasi citra anatomi. Penelitian ini merupakan penelitian kuantitatif eksperimental untuk membandingkan informasi anatomi antara T2WI TSE Fat Saturation dan T2WI Dixon potongan sagittal guna mengetahui informasi anatomi yang terbaik dengan 10 Pasien klinis HNP pada pemeriksaan MRI Lumbal. Hasil menunjukkan bahwa Teknik Dixon lebih unggul dibandingkan dengan Fat Saturation dalam supresi lemak pada klinis HNP, Dixon tampak lebih homogen dalam keseluruhan gambar, akan tetapi terdapat perbedaan waktu akuisisi dari kedua sekuen yang signifikan, Dixon mengahbiskan waktu rata rata 4-5 menit dalam1 sekuen dan Fat Saturation 1-2 menit. Hal ini dapat menjadi sebuah pertimbangan praktisi MRI dalam pemeriksaan MRI Lumbal pada klinis HNP untuk mengurangi motion artefact terhadap pasien HNP dengan gradasi tinggi.

Abstract

Magnetic resonance imaging (MRI) is a diagnostic examination modality in medicine using a magnetic field without using X-rays, MRI has the advantage of being able to create images and can show clearer and more sensitive anatomical differences in soft tissues in the body such as the brain,Bone marrow and musculoskeletal. An MRI machine can produce diagnostic images of the inside of the human body, both in sagittal, coronal and transverse sections, without using ionizing radiation (X-rays) and also without using radioactive substances, but based on the principle of magnetic resonance of the hydrogen atom to reveal anatomy and pathology. clinical diagnosis, one of which is Hernia Nucleus Pulposus in the Cervical vertebrae. Hernia  Nuecleus pulposus is a condition of biochemical ad physical changes in the spinal disc tissue caused by degeneration in old age,or acute external pressure that causes a bulge into the spinal canal,putting pressure on the durameter or nerve roots, thereby triggering symptoms of neurological pain. The use of the Dixon sequence was proposed for the assessment of metaphyseal bone marrow water water content,with a short scan time. Dixon sequence imaging can be used for fat suppression in the extremities and spine, but also quantification of fat in the bones..

Abstract

One of the cancers that causes the highest mortality is nasopharyngeal cancer. The number of nasopharyngeal cancer cases in Indonesia reached 19,943 new cases with a mortality rate of 13,399. Radiotherapy is the main treatment modality and part of standard care for cancer patients. The way radiotherapy works is to damage the DNA chain of tumor cells in order to kill tumor cells directly and eliminate the ability to proliferate. Giving radiation to the head and neck region has an influence on weight loss. The purpose of this study was to describe the BMI (Body Mass Index) of nasopharyngeal cancer patients who underwent IMRT therapy at the Radiotherapy Unit of Prof. Dr. I.G.N.G Ngoerah Hospital. The type of research used is quantitative research with an observational approach using retrospective data. The samples of this study were 25 patients with nasopharyngeal cancer who underwent IMRT therapy from January to December 2021 at the Radiotherapy Unit of Prof. Dr. I.G.N.G Ngoerah Hospital. The results of this study showed 25 samples of nasopharyngeal cancer patients who underwent IMRT therapy experienced weight loss with an average of 13.01 and BMI with an average of 4.93. Based on the results of the Statistical Test which shows that the p value <0.05 which means there is a decrease in body weight in nasopharyngeal cancer patients undergoing IMRT therapy in the Radiotherapy Unit of Prof. Dr. I.G.N.G Ngoerah Hospital. Of the 25 samples of nasopharyngeal cancer patients who underwent IMRT therapy, there were changes in BMI (Body Mass Index) before irradiation and after irradiation. This is evident from the normality test value and Paired Twhich shows a p value <0.05, meaning that there is a decrease in body weight in nasopharyngeal cancer patients undergoing IMRT therapy.

Abstract

Knee injuries are often encountered in general practice and in hospitals. One injury that can occur is injury to the meniscus which causes a meniscus tear. The meniscus is a fibro cartilage disc which is the content of the knee joint and is divided into two, namely the lateral meniscus and the medial meniscus. To confirm the diagnosis of injured ligaments is by carrying out an MRI examination. MRI examination of the knee joint using T2* Multi Echo Rechalled Gradient Echo can provide optimal images in cases of meniscus tears. MRI examination of the knee joint using MEDIC is very useful for cervical imaging, cartilage, joint and musculoskeletal examination. The advantage of the MEDIC sequence is that it can be used for 2D and 3D imaging and can reduce chemical shift artifacts. Based on the journal taken by the author, the sequence needed to clinically show a meniscus tear on an MRI Knee Joint examination is sagittal STIR and sagittal T2 MEDIC. then the most optimal sequence in clinically showing a meniscus tear is chosen to increase the efficiency of the examination time. The type of research used is qualitative research with a case study approach. The subjects used in this research were 3 Radiology Specialist Doctors and 3 Radiographers. The STIR and T2 MEDIC sequences on the MRI Knee Joint examination have their respective roles in confirming the diagnosis of Tear Meniscus. The STIR sequence plays a role in assessing the Anterior Cruriated Ligament, Posterior Cruriated Ligament, radiologists also want to see edema or swelling that occurs in the patient's genu. The MEDIC T2 sequence plays a role in assessing the medial and lateral meniscus, the radiologist also wants to see blood production in the patient's genu. The STIR and T2 MEDIC sequences in the MRI Knee Joint examination at the Balimed Denpasar Hospital installation are able to confirm the diagnosis, especially in the clinical Tear Meniscus, because with these two sequences, the picture of the Medial Meniscus, Lateral Meniscus, Anterior Cruriated Ligament, Posterior Cruriated Ligament, product blood and edema can be clearly seen.
