Abstract
Purpose
It was the aim of our study to evaluate this procedure using pelvic anatomical landmarks
in order to assess the accuracy of fusion imaging and to critically evaluate the applicability
in daily practice.
Methods
In a prospective, single center study, 10 patients with clinical signs of deep infiltrating
endometriosis (DIE) were selected. We measured the distance between the landmark organ
and the target shown by the software system (measurement 1). Measurement 2 depicts
the distance between the landmark and the nearest calibration point. The calibration
inaccuracy was measured as a third type of measurement (measurement 3).
Results
Measurement 1: the average distance between the organ landmark to the target was 13.6
mm (range: 0–96 mm). Measurement 2: in 31 of the 40 attempts (77.5 %), we could measure
the distance from the landmark organ to the nearest calibration point. The average
distance was 34.4 mm (range: 0–69 mm).
Measurement 3: A perfect match was seen in 6 of 20 attempts (30.0 %). There was a
deviation in 14 of the 20 attempts (70.0 %). The mean distance was 11.1 mm (range:
6–23 mm). Conclusion Although very promising, MRI-ultrasound fusion imaging (MUFI)
currently cannot be readily implemented into daily practice as a routine evaluation
of DIE.
