ANALISIS PERBEDAAN KUALITAS CITRA ANTARA SEQUENCE T2 FSE BLACK BLOOD DAN T2 SSFSE BLACK BLOOD POTONGAN SHORT AXIS PADA PEMERIKSAAN CARDIAC MRI

Research Background: In clinical practice, cardiac magnetic resonance (CMR) plays a crucial role in the diagnosis of myocardial oedema according to the 2018 Lake Louise Criteria, particularly through T2-weighted imaging. In this context, myocardial oedema is commonly evaluated using T2-weighted Fast Spin Echo (FSE) and Single-Shot Fast Spin Echo (SSFSE) black-blood sequences in the short-axis plane. The FSE sequence provides good spatial resolution and detailed morphological information but requires a longer acquisition time. In contrast, SSFSE enables very rapid image acquisition, albeit with a potential reduction in spatial resolution and increased image blurring. Subsequently, image quality is then quantitatively assessed using Signal-to-Noise Ratio (SNR) and Contrast-to-Noise Ratio (CNR) as the primary parameters of diagnostic quality.rnResearch Objective: This research aims to analyse and compare the image information and diagnostic performance of T2-weighted Fast Spin Echo (FSE) Black-Blood and T2-weighted Single-Shot Fast Spin Echo (SSFSE) Black-Blood sequences in the short-axis plane in cardiac MRI examinations, in order to evaluate cardiac MRI image quality.rnResearch Design: This research employed a quantitative comparative method. It was conducted using a prospective experimental observational approach, in which all six patients underwent cardiac MRI examinations using both sequences.rnResearch Results: T2-weighted SSFSE Black-Blood demonstrated quantitatively superior image quality in short-axis cardiac MRI compared with T2-weighted FSE Black-Blood. This was evidenced by a 93.7% increase in Signal-to-Noise Ratio (SNR) and an 85.2% increase in Contrast-to-Noise Ratio (CNR), both of which were statistically significant (p 0.05). However, clinical interpretation should still take into account the trade-offs in spatial sharpness and potential image artifacts.rnrnKeywords : Cardiac MRI, T2-weighted FSE Black-Blood, T2-weighted SSFSE Black-Blood, Signal-to-Noise Ratio (SNR), Contrast-to-Noise Ratio (CNR)
