Prosedur Pemeriksaan Multi Slice Computed Tomography Thoraks Guided Pada Kasus Tumor Mediastinum

MSCT Thoraks, Guided, Tumor Mediastinum

Abstract

Background: An accurate examination that can determine the type and stage of a mediastinal tumor is a guided biopsy, which takes a sample of tumor tissue. A thoracic MSCT examination in cases of mediastinal tumors with a guided biopsy is performed with special patient preparation, including a 4-hour fast and urea and creatinine tests. Scanning is not performed once the biopsy needle is inserted into the biopsy site, and the examination uses a 70 cc contrast medium injection at a flow rate of 2-3 ml after sample collection. The purpose of this study was to determine the procedure for a guided thoracic MSCT examination in cases of mediastinal tumors and to determine the rationale for using intravenous contrast medium injection after sample collection in a guided thoracic MSCT examination.
Methods: This research method was descriptive qualitative with a case study approach. Data were collected through observation, documentation, and interviews with three radiologists, three radiographers, related physicians, and the patient's family. The data were then categorized for open coding and interpretation.
Results: The results of this study indicate that guided thoracic MSCT examination in mediastinal tumor cases is performed with a 4-hour fast, urine and creatinine checks, pre-biopsy scans, biopsy procedures, and post-biopsy. The reason the scan was not performed during spinal needle injection was because the tumor area was large and located near the aorta, and to minimize radiation dose. The reason for using contrast media after sampling was to determine the location of the tumor, in addition to determining the presence of pneumothorax and metastasis to other organs.
Conclusions: The procedure for guided thoracic MSCT in mediastinal tumors involves specific preparation and post-sampling contrast injection to accurately locate the tumor and detect complications like pneumothorax or metastasis.
