Inter- and Intra-Observer Variability Assessment of in Vivo Carotid
Plaque Burden Quantification Using Multi-Contrast Dark Blood MR Images.
Studies in health technology and informatics,
113:384-93,
2005.
Note: PMID: 15923749.Abstract: The chapter presents the research to test the hypotheses that (1) vessel wall volume measurements from dark blood MR images with multiple contrast-weightings (T1W, T2W and PDW) are highly reproducible, and that (2) the intra-observer and inter-observer variability of carotid wall volume measurements will be less than those obtained with maximum wall area (MaxWA) measurements. METHODS: Sixteen patients (aged 72 +/- 7years) with carotid stenosis documented by duplex ultrasound were recruited for the study. Dark blood T1W, PDW and T2W MR images were used to measure carotid wall volume and MaxWA by two independent observers for inter-observer and intra-observer variability assessment. RESULTS: The intra-observer absolute difference of carotid wall volume for T1W, T2W and PDW images were 67.3 +/- 47.5 mm(3) (2.3 +/- 1.8\%), 63.2 +/- 52.2 mm(3) (2.0 +/- 1.3\%), and 69.8 +/- 45.2 mm(3) (2.4 +/- 1.7\%) respectively. The inter-observer absolute difference of carotid wall volume for T1W, T2W and PDW images were 103.5 +/- 141.8 mm(3) (3.0 +/- 3.1\%), 95.9 +/- 102.1 mm(3) (3.1 +/- 2.6\%), and 132.1 +/- 87.8 mm(3) (4.3 +/- 2.7\%) respectively. The intra-observer absolute difference of carotid MaxWA for T1W, T2W and PDW images were 6.9 +/- 5.0 mm(2) (4.2 +/- 2.9\%), 5.1 +/- 4.2 mm(2) (3.1 +/- 2.3\%) and 7.5 +/- 4.7 mm(2) (4.2 +/- 2.7\%) respectively. The inter-observer absolute difference of carotid MaxWA for T1W, T2W and PDW images were 9.5 +/- 4.2 mm(2) (5.8 +/- 2.3\%), 6.4 +/- 6.1 mm(2) (3.8 +/- 3.1\%) and 10.8 +/- 7.3 mm(2) (6.1 +/- 3.7\%) respectively. Both intra- and inter-observer variability in carotid volume measurement tend to be smaller than that in carotid MaxWA measurement with intraclass correlation coefficients ranged 0.932 to 0.987 for volume measurement and 0.822 to 0.946 for MaxWA measurement. @ARTICLE{zhang_inter-_2005, author = {Shaoxiong Zhang and Jasjit S Suri and Olivier Salvado and Yiping Chen and Frank K Wacker and David L Wilson and Jeffrey L Duerk and Jonathan S Lewin}, title = {Inter- and Intra-Observer Variability Assessment of in Vivo Carotid Plaque Burden Quantification Using Multi-Contrast Dark Blood MR Images}, journal = {Studies in health technology and informatics}, year = {2005}, volume = {113}, pages = {384-93}, note = {PMID: 15923749}, abstract = {The chapter presents the research to test the hypotheses that (1) vessel wall volume measurements from dark blood MR images with multiple contrast-weightings (T1W, T2W and PDW) are highly reproducible, and that (2) the intra-observer and inter-observer variability of carotid wall volume measurements will be less than those obtained with maximum wall area (MaxWA) measurements.

Correction of intensity inhomogeneity in MR images of vascular disease.
In EMBS'05,

pages 4302-4305,

IEEE.
Abstract: We are involved in a comprehensive program to characterize atherosclerotic disease using multiple MR images having different contrast mechanisms (T1W, T2W, PDW, magnetization transfer, etc.) of human carotid and animal model arteries. We use specially designed intravascular and surface array coils that give high signal-to-noise but suffer from sensitivity inhomogeneity and significant noise. We present here a new non-parametric method for correcting the images without assumption of the number of different tissues. Intensity inhomogeneity is modeled with cubic spline and is locally optimized using an entropy criterion. Validation has been performed on a specially design neck phantom as well as actual MR scans on patient neck. This same algorithm has been successfully applied to the correction of very high resolution, intravascular coil images. The steep bias is corrected sufficiently to aid human interpretation of gray scales. It should also make possible computerized tissue classification @INPROCEEDINGS{salvado_correction_2005, author = {O. Salvado and C. Hillenbrand and D.L.

Partial volume correction using reverse diffusion.
In SPIE'05,
volume 5747 of Image Processing,
San Diego, CA, USA,
pages 625-633,
April 2005.
SPIE.
Abstract: Many medical images suffer from the partial volume effect where a boundary between two structures of interest falls in the middle of a voxel giving a signal value that is a mixture of the two. We propose a method to restore the ideal boundary by splitting a voxel into sub-voxels and reapportioning the signal into the sub-voxels. We designed this method to correct MRI 2D slice images where partial volume can be a considerable limitation. Each voxel is divided into four (or more) sub-voxels by nearest neighbor interpolation. The gray level of each sub-voxel is considered as "materials" able to move between sub-voxels but not between voxels. A partial differential equation is written to allow the material to flow towards the highest gradient direction, creating a "reverse" diffusion process. Flow is subject to constraints that tend to create step edges. Material is conserved in the process thereby conserving MR signal. The method proceeds until the flow decreases to a low value. To test the method, synthetic images were down-sampled to simulate the partial volume artifact and restored. Corrected images were remarkably closer both visually and quantitatively to the original images than those obtained from common interpolation methods: on simulated data mean square errors were 0.35, 1.09, and 1.24 for the proposed method, bicubic, and bilinear interpolation respectively. The method was relatively insensitive to noise. On MRI physical phantom and brain images, restored images processed with the new method were visually much closer to high-resolution counter-parts than those obtained with common interpolation methods. @INPROCEEDINGS{salvado_partial_2005, author = {Olivier Salvado and Claudia Hillenbrand and David L.
