Interobserver Agreement Radiology

  • April 10, 2021

Whole body MRI (MRI) is recommended by the International Myelom Working Group for all patients with asymptomatic myeloma and solitary plasma cytome and the British NICE guideline for all suspected myeloma patients. Some centres that are unable to offer WB MRIs offer low-dose whole CTs (WB-CTs). There are no studies comparing the Interobserver agreement and the detection of contemporary MRI disease (anatomical imaging and DWI) to WB-CT. Our main objective is to compare the interobserver agreement between WB-CT and WB-MRI for the diagnosis of myeloma. Significant differences were noted in the inter-obrirver agreement, as emergency physicians tended to over-diagnose pe. There have been several previous studies that have examined the degree of compliance between experienced radiologists and radiological residents interpreting CTPA in an emergency context [23-25]. Our study shows a good IOA between the interpretation of on-demand radiologists and PE staff with a total agreement of 91.4% (Kappa of 0.81). This is consistent with Shaham et al.`s study, which found that the CTPA`s preliminary interpretations on the request were reasonably accurate (Kappa statistics 0.7 and 0.8), indicating that the interim interpretations of the residents of the PE studies are reasonably accurate [26]. Similarly, Gimberg et al. reported an overall agreement of 93% (kappa 0.8) between radiology fellows and radiology faculties in interpretations of the CTPA [27]. Yavas et al., although they report a good but slightly lower correlation (0.7 of Kappa statistics) between residents and experienced radiologists, suggests that long-term definitive treatment is not solely based on per capita reading [28]. Our results also apply to PE sites, as while the study was interpreted as positive, there was a good match on the position of pulmonary embolism between staff and the local resident on demand. Magnetic resonance imaging (MRI) is the gold standard for assessing cartilagine and meniscal lesions, band integrity and bone marrow edema [5].

MRI is a non-invasive diagnostic tool with multiplanar capabilities, exceptional soft tissue resolution and moderate sensitivity (42-77%) and high specificity (80-92%) Detection of chondrale lesions [6, 7].
