Final Programme

A-228 09:15
PET/CT in esophageal and GI cancer
E. Bombardieri; Milan/IT
Learning Objectives:
1. To demonstrate the value of PET in characterising cancer.
2. To describe the impact in patient management.
3. To defi ne the value of PET/CT over the conventional imaging.
Postgraduate Educational Programme
A-229 09:35
Response evaluation criteria in solid tumors (RECIST): Volumetric method and functional parameters
H.-O. Peitgen; Bremen/DE
Learning Objectives:
1. To learn about fundamental benefi ts of 3D volumetry in contrast to 2D measurements for the estimation of
tumor growth.
2. To understand that volumetric measurements provide subvoxel accurate lesion size assessment whereas
diameter based estimates suffer from high risk of misclassifi cation.
3. To understand the infl uence of error propagation on the computation of change rates.
4. To learn about state of the art tumor perfusion analysis with dynamic contrast enhanced MR imaging.

B. How to objectively characterise and compare the performances of conventional and digital
detectors
F.R. Verdun, P. Monnin; Lausanne/CH
Learning Objectives:
1. To defi ne the basic parameters of image quality for conventional and digital detectors.
2. To present methodologies to assess MTF (pre-sampled and expected MTFs), NPS, NEQ and DQE.
3. To illustrate the effect of beam quality and detector entrance dose on detectors’ effi ciency (DQE).
4. To discuss advantages and limitations of detector assessments by means of alternative methods such as
the use of contrast-detail test-objects.
