“…Of these, 58 were described only within the methods section of a particular systematic review . A further five tools to assess the quality of studies included in systematic reviews were presented in publications dedicated to these tools [4,[66][67][68][69]. Four additional tools had been developed to assess the quality of studies of diagnostic accuracy in general [70][71][72][73].…”

“…To optimize the methodology and to cope with population biases in radiological studies, our prospective study had to meet a high score on the scale of methodological quality (SMQ) for clinical studies of radiological examinations proposed by Arrivé et al [4]. We applied the 15 SMQ standards (SMQS) they defined to our study.…”

Accuracy of MRI in characterization of soft tissue tumors and tumor-like lesions. A prospective study in 548 patients

The purpose of our study was to assess prospectively the value of MRI in characterization of soft tissue tumors (STT) and soft tissue tumor-like lesions in a multi-institutional setting by a group of experts. The material consisted of 548 untreated and proven STT or tumor-like lesions originating from a multi-institutional database of STT in which 930 consecutive patients with STT examined by MRI were registered between 1 January 2001 and 28 April 2003. Based on MRI findings, a suitably ordered differential diagnosis was made in consensus by two radiologists (J.L.M.A.G and A.M.D.S). MRI diagnoses were compared with histology results (455 cases, 83%) and/or 6-month follow-up (93 cases, 17%) as reference standards. The correlation between the MRI and histological diagnosis and between the radiological and histological phenotype were statistically determined. One hundred twenty-three patients presented with a malignant STT; 425 patients presented with a benign one. Concerning differentiation between malignant and benign lesions (dignity), a sensitivity of 93%, specificity of 82%, negative predictive value (NPV) of 98% and positive predictive value (PPV) of 60% with accuracy of 85% were obtained. Concerning phenotype characterization, if only the first MRI diagnosis was taken into account, a sensitivity of 67%, specificity of 98%, NPV of 98%, PPV of 70% and accuracy of 96% were obtained. For benign lesions, sensitivity of 75%, specificity of 98%, NPV of 98%, PPV of 76% and accuracy of 97% were obtained. The phenotype's definition of malignant STT had a sensitivity of 37%, a specificity of 96%, NPV of 96%, PPV of 40% and an accuracy of 92%. A correct diagnosis compared with histological assessment was proposed in 227(50%) of the 455 histologically confirmed cases. Despite non-quantified MR parameter evaluation, the results of our prospective study were better than those reported in previous studies and demonstrated the need for a centralized approach to such rare pathology.

“…The transverse planes were angled perpendicular to the long axis of the tumor by using the sagittal plane (11). The imaging parameters for the T1-weighted sequences were a 15 cm field of view, a 4 mm section thickness, a 1 mm intersection gap, 500-582/9.5-13 (19). p values less than 0.05 were considered statistically significant.…”
