Better techniques can help determine management and predict outcome

O ver the past decade several clinical applications
of magnetic resonance imaging have been developed for benign and
malignant conditions of the pelvis. The production of easily
recognisable multiplanar images of high soft tissue contrast
without
the operator dependence of ultrasonography or the ionising radiation of
computed tomography
well suit magnetic resonance imaging for such
tasks. Attractive though the technique appears, we must demand more
from such an expensive
and still scarce
resource.
The applications of magnetic resonance imaging in the pelvis have
received great scrutiny. Several large prospective studies have been
performed comparing pelvic magnetic resonance with surgical specimens
sectioned and analysed in the planes used for imaging. Its diagnostic
performance is thus well validated for cancer of the rectum, cervix,
and prostate.1-3 Its key advantage is prediction of local
extension of cancer beyond the primary organ. Here, magnetic resonance
imaging competes with tried and tested clinical methods such
