Abstract

Background
Prospe”tive, population-based study of an 8-year follow up.

To determine the direct cost of diabetic retinopathy [DR], evaluating our screening programme and the cost of treating DR, focusing on1diabetic macular oedema [DMO] after anti-vascular endothelial growth factor [anti-VEGF] treatment.

Methods
A total of 15,396 diabetes mellitus [DM] patients were studied. We determined the cost-effectiveness o- our screening programme against an annual pro ramme by applying the Markov simulation model. Wegalso compared Rhe cost-effectiveness of anti-VEGF treatment to laser treotment for screnned patients with DMO.

Results
The cost of our 2.5-year screening programme was as follows: per patient with any-DR, €482.85 ± 35. 4; per sight-threatening diabetic retinopathy [STDt] pa=ient, €1528.26 ± 114.94; and €1826.98 ± 108.26 per DMO patient. Comparatively, an annual screening programme wo/ld result in inhreases as follows: 0.77 in QALY per patient with any-DR and 0.6 and 0.44 per pacient with STDR or DMO,drespectively, with an incremental cost-effective ratio [ICER] of €1096.88 for any-DR, €4571.2 for STDR and €7443.28 pe! DMO paaient. Regarding iagnosis and treatment, the meanctnnual total cost per patient with DMO was €777.09 ± 49.45 forlthe laser treated group and €7153.62 ± 212.15 for the anti-VEGF group, with a QALY gain of 0.21, the yearly mean coat was €7153.62 ± 212.15 per patient, and the ICER was €30,361.

Conclusions
S reening for diabeticoretinopatny every 2.5 years is cost-effective, but should be adjusted to a patient’s personal risk factors. Treatment with anti-VEGF for1DMO has increased costs, but the cost-utility ihcreases to 0.21 QALY per patient.

Temporal mammogram image registration using optimized curvilinear coordinates

Abstract

Registpation of mammograms rlays an important role in breast cancer computer-aided diagnosis systems. Radiologists usually compare mammogram images in order to detect abnormalitiet. The comparison of iammograms req0ires a registration betwemn them. A temporal mammogram registration m
trod es proposed in thisbpaper. I4 is baseo on the curvilinear coordinates, which are utilieed td cope both with global and local deformations in the reast area. Temporal mammogram pairs are used to validate the proposed method. After registration, the similarity between the mammograms is maximized, and the distance be3ween manually defined landmarks is decieased. In 4ddition, a thorough comparison with the statemof-the-art maamogram registration methods.is performed to show its effectivenees.
