Analisis Prosedur Pemeriksaan CT Scan Abdomen Tiga Fase Pada Klinis Adenocarcinoma Colon Metastasis Hepar Di RSUP Persahabatan Jakarta Timur

Background: CT scans can be used as a supporting tool to evaluate various abnormalities and determine certain clinical conditions, one of which is that abdominal examination is used to make clinical diagnoses such as liver metastatic colon adenocarcinoma. Three-phase abdominal examination technique for clinical adenocarcinoma colon liver metastases carried out at Persahabatan Hospital using intravenous injection of contrast media without oral and rectal use with a delay time technique. Results: The three-phase abdominal CT scan examination procedure for clinical adenocarcinoma colon metastases to the liver was carried out using the Abdomen_3Phase protocol with a helical type scan with intravenous administration of contrast media which was sufficient to confirm the diagnosis with post-contrast scanning, namely in the arterial phase using a delay of 22-25 seconds, for the venous phase, that is 50-60 seconds, then for the equilibrium/delayed phase, that is 90-100 seconds from the beginning of the introduction of the contrast medium which is reconstructed into a 5 mm slice thickness sagittal and coronal section. A three-phase abdominal examination is carried out to evaluate abnormalities in the abdomen such as intra-abdominal masses so that it can differentiate between masses and metastases. Conclusion: The technique of inserting contrast media into a three-phase abdominal examination in clinical adenocarcinoma colon liver metastases at the radiology installation at Persahabatan Hospital, East Jakarta is carried out intravenously and is sufficient to confirm the patient's diagnosis. This is done because the focus is on assessing the liver, where the liver is a dense cavity. so that to assess abnormalities in the liver, contrast media can be injected intravenously, and for the condition of the colon, it can be assessed in general terms without going oral or rectal

ANALISIS PENGARUH VARIASI WINDOW WIDTH DAN WINDOW LEVEL TERHADAP KUALITAS CITRA PADA PEMERIKASAAN CT SCAN THORAX DENGAN KASUS TUMOR PARU DI RUMAH SAKIT IBNU SINA YW-UMI MAKASSAR

Tujuan dari penelitian ini adalah untuk menganalisis pengaruh variasi window dan window level terhadap kualitas citra pada pemerikasaan CT Scan thorax dengan Kasus tumor paru di rumah sakit Ibnu Sina YW-Umi Makassar. Jenis penelitian ini adalah penelitian kuantitatif dengan pendekatan eksperimen, yang bertujuan untuk mengetahui pengaruh variasi Window Width dan Window Level terhadap kualitas citra pada pemeriksaan CT Scan Thorax dengan kasus tumor paru menggunakan variasi Window Width 400 HU dengan Window Level 40 HU, Window Width 350 dengan Window Level 50 HU, dan Window Width 360 HU dan Window Level 37 HU. Pada hasil penelitian menyatakan bahwa hasil mean rank uji friedman test diketahui nilai variasi Window Width 360 HU dengan Window Level 37 HU memiliki nilai tertinggi yaitu 2.47 yang menunjukkan bahwa Window Width 360 HU dengan Window Level 37 HU adalah Window Width dan Window Level yang paling optimal dalam menampakkan kualitas citra pemeriksaan CT Scan Thorax pada kasus tumor paru
