<![CDATA[The heart is an important organ in the body because it has a vital role in maintaining human life. However, it cannot be denied that the heart can experience damage, one of which is Coronary Artery Disease (CAD), which is characterized by the presence of plaque in the coronary arteries so that the coronary arteries become narrow. There are several causes that can cause CAD, but this needs to be examined further to find out the main cause of the disease so that the treatment given can be appropriate and fast. One treatment that can be used to check CAD is via CT Scab Cardiac. However, the study regarding this examination has not been studied further, so researchers want to study the analysis of cardiac CT scan examinations with clinical Coronary Artery Disease (CAD) in the Radiology Installation of the NTB Provincial Hospital. The aim is to carry out an in-depth analysis of cardiac CT scan examinations with clinical Coronary Artery Disease (CAD) in the Radiology Installation of the NTB Provincial Regional Hospital, so that various information related to this matter can be known in depth. The research method used is qualitative with a case study approach. The data collection technique was carried out through observation, interviews and documentation from June to July 2023. The data collected was then analyzed in depth so that the research results showed that the CT Cardiac examination using the bolus tracking technique was carried out with 80 ml of contrast media and 40 ml of saline flush with The injection duration is 40 seconds and starts with a dual service AP Lateral topogram, calcium scoring scanning without contrast media, placing the locator 2 cm above the carina, placing the tracker on the descending aorta followed by cardiac scanning with several phases.

<![CDATA[Background: Thyroid tumors are abnormal growths of the thyroid gland, which can be benign or malignant tumors such as papillary, follicular, medullary or anaplastic types (Aldino, 2018). CT scan of the neck according to (Lee at al, 2016) The contrast media used consists of 80 ml of non-ionic contrast media followed by 20 ml of saline given through the antecubital vein using a power injector and a 20 gauge intravenous catheter at a speed of 2.5- 3.0 ml/sec. According to (Yang et al., 2016) 80-100 ml of 300 mg/L omnipaque contrast media is injected through the cubital vein at a rate of 2.7-3.0 mL/s. And according to (Deng et al., 2019), 80 ml of iopromide (300 mgl/mL) contrast media is injected intravenously at a rate of 3 ml/sec. The aim of this research is to determine the procedure for a CT scan of the neck with contrast in cases of thyroid tumors in the radiology installation at the NTB Provincial Regional Hospital. Method: The type of research carried out is qualitative research with a case study approach. Data were collected by observation, interviews with one radiologist and three radiographers and documentation. Data collection was carried out from June to July 2023. Data analysis was carried out using an interactive model system. Results: This study shows that the contrast media used in CT scans of the neck uses 50 ml contrast media on the grounds that 50 ml contrast media can confirm the diagnosis because in the case of tumors in the thyroid you only want to see whether there is enhancement of the tumor. And the contrast media injection is carried out manually by a radiology nurse on the grounds that it is sufficient to confirm the diagnosis if it is carried out with proper control so that the examination is simpler and the processing time is faster. Conclusion: There is a difference in the CT scan of the neck between theory and the NTB provincial hospital where in theory Lee et al (2016) explains that 80 ml of contrast media is used and an injector is used at a speed of 2.5-3.0 ml/s while the provincial hospital NTB uses 50 ml contrast media and is injected manually by a radiology nurse on the grounds that this can confirm the diagnosis.]]>

<![CDATA[Background. Non-contrast head CT scans utilizing X-rays are considered the gold standard in emergency units for patients with clinical head injuries. Rotation time is a parameter that influences the radiation dose received by patients. This study aims to evaluate the impact of rotation time on patient radiation doses, emphasizing the ALARA principle. The research findings can assist in optimizing CT scan settings to reduce radiation doses without compromising image quality.. Methods: This quantitative research employs an experimental approach to investigate the influence of rotation time variations on CTDI (CT dose index) and DLP (dose leght product) in non-contrast head CT scans. Results: Calculation of CTDI and DLP values to assess the impact of rotation time variations, using two variations, 1 s and 1.5 s, yielded the following results: CTDI and DLP for 1 s were 20.30 mGy and 239.54 mGycm, respectively, while CTDI and DLP for 1.5 s were 20.43 mGy and 249.26 mGycm. Conclusion: Rotation time variations affect CTDI and DLP values in non-contrast head CT scans, although both values tend to remain stabel. A rotation time of 1 s is considered optimal for CTDI and DLP in non-contrast head CT scans at the Radiology Department of Sunset Vet Kuta Animal Hospital.]]>

<![CDATA[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 α (<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]]>

<![CDATA[Background: Shoulder Joint MRI examination is one of the musculoskeletal examinations that is often carried out in the MRI modality because the Shoulder joint is one of the most active joints. In order to be able to visualize a good image, the right coil is needed, in the shoulder joint MRI examination it is recommended to use a shoulder array coil or shoulder coil. This examination can also use a flex coil in an MRI shoulder joint examination at the hospital if the congenital shoulder coil is damaged. The shoulder coil has better image quality because of its shape that surrounds the entire object you want to examine. Methods: This study used a quantitative approach with a quasi-experimental approach, namely conducting experiments on the observed objects, to find answers to the problems raised by conducting an MRI Shoulder Joint examination using two different types of coils, namely Shoulder coil and flex coil in 10 samples. The data is then processed using SPSS. Results and Conclusions: Based on the results of statistical test calculations for the SNR value of the anatomy of the shoulder joint, there is a significant difference in image quality, namely the SNR of the anatomy of the shoulder joint using shoulder coil and flex coil which has an overall p value/sig of 0.038 so that Ho is rejected and Ha is accepted. The average SNR for shoulder coil was 312.41 and flex coil was 246.30, so the difference in the SNR value for MRI shoulder joint using shoulder coil compared to flex coil was 66.11. With these results, the more optimal MRI Shoulder joint examination uses the Shoulder coil. Keywords: Shoulder Coil, Flex Coil, Signal to Noise Ratio (SNR)]]>
