Abstract

Anterior talofibular ligament (ATFL) injury is one of the most common ligament injuries affecting the ankle joint and can lead to chronic ankle instability if not properly evaluated. Magnetic Resonance Imaging (MRI) is an imaging modality with excellent capability for visualizing soft tissue structures, including ligaments, tendons, and periarticular tissues. This study aimed to analyze the ankle MRI examination procedure using a head coil in patients with suspected ATFL injury at the Radiology Unit of RSU Prima Medika Denpasar. A descriptive qualitative method with a case study design was employed, involving three patients with suspected ATFL injury who underwent ankle joint MRI using a head coil. Data collection took place in April 2026 through direct observation, interviews with radiographers and radiologists, and documentation of examination protocols and MRI images. The examination protocol included the following sequences: STIR FSE transverse, STIR FSE sagittal, PD FSE transverse SPAIR, T2 FSE sagittal, STIR FSE coronal, T1 FSE coronal, PD FSE sagittal FS, and PD FSE coronal FS. The results demonstrated that using a head coil produced image quality sufficient for evaluating ankle joint anatomy and ATFL abnormalities. Proton Density Fat Saturation (PD FS) sequences provided optimal ligament visualization and revealed signal intensity changes associated with ligament injury, while STIR sequences were effective in detecting soft tissue and bone marrow edema accompanying ankle injuries. Based on observations and interviews, the use of a head coil serves as a viable alternative for ankle joint MRI in cases of suspected ATFL injury when a dedicated ankle coil is unavailable, provided that proper positioning and optimal sequence selection are implemented.

Abstract

Quality control testing of X-ray equipment is necessary to ensure proper equipment performance and optimal diagnostic image quality. The collimator is an important component that limits the radiation field; therefore, the congruence between the light field and X-ray radiation field must be regularly evaluated. This study aimed to determine the results of collimator congruence testing on a stationary radiographic X-ray unit at the Radiology Installation of RSUP Prof. dr. I.G.N.G. Ngoerah. This quantitative study employed an observational approach, in which data were obtained through direct observation of collimator testing using a Collimator Test Tool and a Beam Alignment Test Tool. The tests evaluated the congruence between the light field and X-ray radiation field and the perpendicularity of the X-ray beam to the light field center at an FFD of 100 cm. The results showed deviations of 1.0% FFD on the X-axis and 0.6% FFD on the Y-axis, with a total deviation of 1.6% FFD. These results were within the tolerance limits of ΔX ≤ 2% FFD, ΔY ≤ 2% FFD, and ΔX + ΔY ≤ 3% FFD. The perpendicularity test showed a deviation of 1.5°, which was within the tolerance limit of ≤ 3°. Therefore, the light field and X-ray radiation field congruence and X-ray beam perpendicularity met the applicable quality control standards. The collimation system was functioning properly and supported image quality and patient radiation safety.

Abstract

Perianal fistulas is a chronic anorectal disease characterized by the formation of an abnormal channel between the anal canal and the perianal skin. Magnetic Resonance Imaging (MRI) is the gold standard imaging modality in the evaluation of perianal fistula because it is able to performed the anatomy of the fistula, the primary and secondary pathways, and the relationship of the fistula to the sphincter complex in detail. However, in clinical practice, difficulties are still found in correlating the location of the eksternal lesions found during clinical examination with the anatomical features on MRI images. One effort that can be done to assist clinical and radiological correlation is the use body marker gel capsules as eksternal markers. This study aims to determine the role of body marker gel capsules in MRI examinations of perianal fistula in the Radiology Department of RSUD Sanjiwani Gianyar. This study uses a descriptive method with a qualitative approach. Data collection was carried out through observation of MRI examination procedures for perianal fistula using a 1,5 Tesla Philips MRI, interviews with two radiographers MRI and two radiologists, and documentation of MRI image results of perianal fistula pariens who used body marker gel capsules. Data were analysed descriptively through data reduction, data presentation, and conclusion drawing. The results showed that the gel capsule body marker acts as an eksternal anatomical marker that helps identify the location of the eksternal fistula lesions, improves the correlation between clinical findings and radiological images, and supports the interpretation of the fistula path on MRI images. The use of the gel capsule body marker also provides additional anatomical references that assist radiographers and radiologists in a more comprehensive evaluation of perianal fistulas.

Abstract

Positron Emission Tomography/Computed Tomography menggunakan fluorine-18 fluorodeoxyglucose merupakan salah satu modalitas pencitraan molekuler yang penting dalam bidang onkologi karena mampu memberikan informasi metabolik dan anatomi untuk diagnosis, penentuan stadium, evaluasi respons terapi, serta pemantauan kekambuhan kanker. Standardized Uptake Value digunakan sebagai parameter semi-kuantitatif untuk menilai uptake fluorine-18 fluorodeoxyglucose pada jaringan atau lesi. Kadar glukosa darah merupakan salah satu faktor fisiologis yang berpotensi memengaruhi distribusi dan uptake radiofarmaka, namun hubungannya dengan Standardized Uptake Value dapat bervariasi bergantung pada karakteristik pasien, kondisi metabolik, karakteristik lesi, serta faktor teknis pemeriksaan. Penelitian ini bertujuan untuk menganalisis hubungan antara kadar glukosa darah sebelum pemeriksaan dengan Standardized Uptake Value pada pemeriksaan Positron Emission Tomography/Computed Tomography menggunakan fluorine-18 fluorodeoxyglucose onkologi di rumah sakit umum pusat di Surabaya, Indonesia. Penelitian ini menggunakan desain kuantitatif korelasional dengan pendekatan cross-sectional. Sampel penelitian terdiri dari 30 pasien yang menjalani pemeriksaan Positron Emission Tomography/Computed Tomography onkologi menggunakan fluorine-18 fluorodeoxyglucose. Variabel yang dianalisis meliputi kadar glukosa darah sebelum pemeriksaan dan Standardized Uptake Value yang diperoleh dari hasil pencitraan. Analisis data dilakukan menggunakan uji normalitas Shapiro-Wilk dan uji korelasi Pearson. Rerata kadar glukosa darah adalah 101,43 ± 14,59 mg/dL dengan rentang 76–138 mg/dL, sedangkan rerata Standardized Uptake Value adalah 3,52 ± 0,53 dengan rentang 2,53–4,67. Hasil uji Shapiro-Wilk menunjukkan bahwa kadar glukosa darah dan Standardized Uptake Value berdistribusi normal, masing-masing dengan nilai p = 0,153 dan p = 0,403. Hasil uji korelasi Pearson menunjukkan tidak terdapat hubungan yang signifikan antara kadar glukosa darah dan Standardized Uptake Value, dengan nilai r = -0,046 dan p = 0,809. Penelitian ini menyimpulkan bahwa kadar glukosa darah sebelum pemeriksaan tidak berkorelasi secara signifikan dengan Standardized Uptake Value pada sampel yang diteliti. Variasi Standardized Uptake Value kemungkinan dipengaruhi oleh faktor lain seperti berat badan, karakteristik lesi, waktu uptake, aktivitas injeksi, protokol pencitraan, dan kondisi metabolik pasien.
