The most frequent illness of the urinary system is kidney stone disease. Men in their 20s and 30s make up the vast majority of patients. An alternative to CT imaging for kidney stones is MRI, which avoids radiation risks. Since of this, traditional clinical imaging cannot catch the MR signal before it decays, because the echo times (TE's) utilised in this kind of imaging are too long. The goal of this study is to assess the effectiveness of MRI and CT in the detection of kidney stones. Methods: Those who had a kidney stone on plain X-ray, ultrasonography, or CT were part of our research. A nod of approval from the Benha University Institutional Review Board was received before the research could begin (IRB). There were 36 patients in our study, and each one signed an informed consent form after learning about the details of our research. CT and MRI scans were performed on each of them. Age ranged from 19 to 61, with 72.2 percent males and 27.8 percent females in our study sample. Workers accounted for 41.7% of the population, followed by housewives 22.2%, farmers 19.4%, and employees 16.7%. Stone density ranged from 815.63 to 340.99, with a low of 159 and a maximum of 1500, while the stone size ranged from 14.91 to 8.67, with a minimum of 6 and a maximum of 55. In contrast, the distribution of stone size and density by MRI was 15.648.16 with a minimum of 10 and a maximum of 50, respectively. We found that MRI was only able to identify 25 of the 36 instances discovered by the gold technique (CT). This indicates that MRI has a low sensitivity when it comes to stone identification (69.4 percent ). The difference in stone size and density found by CT and MRI, when compared just those instances sharing positive, was extremely significant. Although CT is the gold standard for the diagnosis of renal stones because of its high sensitivity for their direct detection, MRI also plays an important role in their identification. More sequences are needed to inhibit fat in this function, which is dependent on stone size (more than 1 cm), stone position (upper or lower pole). Although CT may identify and quantify urinary tract dilatation, wall thickness, edoema and other downstream consequences of clinically active urinary stones, MRI may be more sensitive and specific in detecting and measuring these secondary effects.
