![]() This study found a significant correlation between the mean of ADC value and the OS histopathologic results as well as the correlation between the mean of ADC value and ME. However, the mean of TIC %slope of OS was (45.3%/s), where the highest result was found in the osteoblastic subtype (70.8%/s) followed by small cell subtype (60.8%/s) and the mean of ME of OS was 100.55% with the highest values was in osteoblastic subtype 172.72% followed by chondroblastic subtype (144.92%). Results: The mean of ADC values of OS was (1.031x10-3☐.31mm2/s), where the highest value was found in chondroblastic subtype (1.470 x10-3☐.31mm2/s). Through SPSS 21 software, the data was analyzed. TIC curve was analyzed and slope value was obtained afterward. The inter-observer agreement was evaluated by Kappa test. ![]() In this case, as many as six obtained ROIs were averaged. It was observed by two radiologist observers with more than 10 years of experience. Moreover, the interpretation was conducted by placing three regions of interest (ROI) in determining ADC value. Methods: This was a retrospective study with observational analysis on OS patients. This study aimed to determine the correlation between ADC and TIC analysis using %Slope and maximum enhancement (ME) of histopathological osteosarcoma subtypes. Magnetic resonance imaging with dynamic contrast enhancement (DCE-MRI) studies was used to determine the apparent diffusion coefficient (ADC) value and the slope of the time-intensity curve (TIC). Thus, contrast-enhanced MRI is a very useful modality in the diagnosis and evaluation of osteosarcoma. Background: According to WHO criteria, osteosarcoma (OS) consists of various histopathological subtypes.
