Abstract

Posteranterior (PA) chest radiographic examination is a support in screening for the diagnosis of lung cancer. Computed radiography (CR) modality can produce chest images quickly, optimally and can be processed as needed. However, so far radiologists interpret images only by visual assessment, so the results are very subjective. Therefore digital medical image processing can be done by looking at the histogram and gray scale values to increase the accuracy of enforcing patient diagnoses. This study aims to analyze the comparison of histograms and gray degree values on CR chest images between normal patients and lung cancer patients. The study was conducted using 30 chest images consisting of normal and lung cancer patient groups with 15 images each. All images are calculated grayscale and display histogram graphics with the Image-J application and statistically analyzed using the Independent T-Test. The results show that there is a difference in grayscale values between normal chest images and lung cancer (p<0.001). The grayscale and histogram values on lung cancer chest images ( 103.2908 + 6.119 ) are higher and tend to the right compared to the grayscale and histogram values on normal chest images ( 64.5848 + 3.28) . Histogram and grayscale values add objective image interpretation in diagnosing lung cancer.

Abstract

Fat Saturation has two modes, namely Weak Mode and Strong Mode, thus further research is needed to determine whether there is a difference in image quality between the two. This study aims to identify the difference in image quality between T2 TSE Fat Saturation Weak Mode and Strong Mode in lumbar MRI for cases of Herniated Nucleus Pulposus (HNP). Data collection was conducted from October to November 2024 at the Radiology Department of SMC Telogorejo Hospital using a Siemens 1.5T MRI scanner. A total of ten patient images were analyzed by calculating the Signal to Noise Ratio (SNR) values in the anatomical structures of the Bone Marrow, Intervertebral Disc, CSF, and Spinal Cord using Radian DICOM Viewer. Statistical analysis was performed using SPSS. The Wilcoxon test showed a significant difference only in the Bone Marrow anatomy (p < 0.05). No significant differences were found in the Intervertebral Disc, CSF, or Spinal Cord (p > 0.05). The Weak Mode also provided a faster scanning time, making it more recommended for lumbar MRI examinations in HNP cases, especially since its image quality is nearly equivalent to Strong Mode for most anatomical structures. This study indicates that there was no significant difference in the Intervertebral Disc anatomy, which is the primary location of HNP. Therefore, Weak Mode is more recommended as it offers greater patient comfort through shorter examination time.
