| description | Breast cancer incidence is rising and so as the caseloads of the radiologists to intezpzet the
mammograms and breast ultrasounds. In an effort to help the radiologis1s, Med Expert was
developed
Objective:
To determine the usefulness ofMed Expert in differentiating breast lesions on mammogram
and breast ultrasound by trainee radiologist by comparing the radiologist report and the was compared to the histology I cytology report. The sensitivity, specificity, positive
predictive and negative predictive values of radiologist and the trainee radiologist were
calculated.
Result
The sensitivizy, specificity and accuracy of radiologist for mammogram intetpretation were
90%, 700At and 77.5% respectively. For ultrasound it was 96.7%, 72.90/o and 82.1%. The
sensitivity, specificity and accuracy of trainee radiologist for intetpretation of mammogram
with the aid of Med Expert were 800/o, 96% and 90% respectively. For ultrasowd it was
900/o, 83% and 85.90At respectively There was lower sensitivity but higher specificity
obtained by the trainee radiologist using Med Expert compared to the radiologist
interpretation However, the overall accuracy of trainee radiologist using Med Expert was
higher compared to radiologist The kappa agreement between the radiologist and trainee
radiologist for mammogmm was 0.6 and that for the ultrasound was 0.8.
Con elusion
Med Expert. was useful in diffexentiaring benign and malignant breast lesions. The txainee
radiologist was able to provide a higher accuracy of interpretation for both mammogmm and
ultrasound, with the aid of the system, compared to the radiologist
trainee tadiologist interpretation with the aid ofMed Expert with histopathology or cytology
results.
Methodology:
EtbicaJ approval obtained. This cross sectional study was conducted in Hospital University
Sains Malaysia in the period of 18 months starting :from June 2006 till November 2007. A
total of 85 patients who had breast lumps and had mammogram and or ultrasound and
biopsies done were recruited in the study. The initial mammogram and breast ultrasound
report was compared with the histology I cytology report. These images were subsequently
re-reported by the trainee radiologist using Med Expert and the output :from the system |
