Abstract

A technique is presented, with two sets of newly designed drills, that facilitates three-dimensional guided insertion of implants. A radiographic guide has been fabricated with titanium markers that are transferred into the CT scan reformatted images. The resulting cross-sectional and panoramic reformatted images provide the precise location for each implant. The buccolingual and mesiodistal inclinations of each implant are measured and transferred to a surgical guide that contains steel drill guide tubes. The starting point and three-dimensional orientation of each implant is then transferred to a pilot osteotomy. The widening of an osteotomy, with end-cutting drills of the usual design, can lead to the loss of orientation because a wider drill cannot be effectively guided by a smaller diameter osteotomy. A newly designed set of drills has been developed that maintains tracking of the original orientation as the incremental increase in width proceeds. The three-dimensional guidance system for implant insertion was first accomplished in vitro and then on patients.

High-field magnetic resonance imaging of meniscoids in the zygapophyseal joints of the human cervical spine.

STUDY DESIGN: Prospective in vitro study of meniscoids in the cervical zygapophysial joints. OBJECTIVES.: To assess the use of high-field magnetic resonance imaging (MRI) as a potential tool for evaluating meniscoids of the cervical zygapophysial joints. SUMMARY OF BACKGROUND DATA: Pain originating from the cervical spine is a frequent condition. It has been suggested that pathologic conditions of meniscoids within the zygapophysial joints may cause pain. METHODS: Six zygapophysial joints from one embalmed human body were investigated with a 3.0-T MR unit, equipped with a microimaging-set. MRIs were correlated with microanatomical sections. RESULTS: High-quality images of the meniscoids were obtained for all joints examined. There was a good correlation between the anatomic features derived from MRI and the microanatomical sections. CONCLUSIONS: High-field MRI was successfully implemented as a noninvasive method for imaging the meniscoids in cervical zygapophysial joints. The results of this in vitro study indicate that high-field MRI may be feasible in evaluating patients with cervical pain possibly related to meniscoid pathology.

Digimouse: a 3D whole body mouse atlas from CT and cryosection data.

We have constructed a three-dimensional (3D) whole body mouse atlas from coregistered x-ray CT and cryosection data of a normal nude male mouse. High quality PET, x-ray CT and cryosection images were acquired post mortem from a single mouse placed in a stereotactic frame with fiducial markers visible in all three modalities. The image data were coregistered to a common coordinate system using the fiducials and resampled to an isotropic 0.1 mm voxel size. Using interactive editing tools we segmented and labelled whole brain, cerebrum, cerebellum, olfactory bulbs, striatum, medulla, masseter muscles, eyes, lachrymal glands, heart, lungs, liver, stomach, spleen, pancreas, adrenal glands, kidneys, testes, bladder, skeleton and skin surface. The final atlas consists of the 3D volume, in which the voxels are labelled to define the anatomical structures listed above, with coregistered PET, x-ray CT and cryosection images. To illustrate use of the atlas we include simulations of 3D bioluminescence and PET image reconstruction. Optical scatter and absorption values are assigned to each organ to simulate realistic photon transport within the animal for bioluminescence imaging. Similarly, 511 keV photon attenuation values are assigned to each structure in the atlas to simulate realistic photon attenuation in PET. The Digimouse atlas and data are available at http://neuroimage.usc.edu/Digimouse.html.

Coronary artery stenosis quantification using multislice computed tomography.

RATIONALE AND OBJECTIVES: Reliable noninvasive detection of stenoses with multislice computed tomography (MSCT) is feasible. This study's aim was to analyze the agreement, correlation, and reliability of MSCT with conventional coronary angiography as the reference standard for quantification of coronary artery stenoses. MATERIALS AND METHODS: A total of 118 significant (at least 50%) coronary artery stenoses with a reference vessel diameter of at least 1.5 mm in 62 patients were analyzed by MSCT using 16 detector rows (Aquilion, Toshiba, Otawara, Japan), multisegment reconstruction, and voxel sizes of 0.35x0.35x0.5 mm. The degree of stenosis on MSCT and quantitative coronary angiography (QCA) was measured by correlating the difference between the reference vessel diameter (average of 2 measurements directly proximal and distal to the stenosis) and the stenotic vessel diameter to the reference vessel diameter. RESULTS: Correlation between the percent diameter stenosis determined by MSCT (78.2+/-13.6%) and QCA (76.0+/-14.8%) was significant (P<0.001) but only moderately so (R=0.51). Bland-Altman analysis revealed no systematic under- or overestimation with MSCT but large limits of agreements (+/-27.6%). Also the limits of agreement for interobserver agreement (reliability) of MSCT data were considerably large (+/-24.8%). Among the 27 coronary artery stenoses with a reference diameter of at least 3.5 mm, there was improved correlation (R=0.80) and the limits of agreement between MSCT and QCA were significantly smaller (+/-17.3%, P<0.008). The agreement between MSCT and QCA was not significantly different for stenoses with no calcification or only calcium spots (+/-28.2%) as compared with those with moderate-or-severe calcifications (+/-27.3%; P=0.8). MSCT allowed correct classification of coronary stenoses into low-grade (below 75%) and high-grade stenoses (at least 75%), in 62% (73 of 118). CONCLUSIONS: The accuracy and reliability of coronary artery stenosis quantification with MSCT using isotropic voxel sizes and multisegment reconstruction is still too low to recommend routine clinical application because of rather low agreement, correlation, and reliability. Despite these limitations, the current results demonstrate the potential of MSCT for reliable and accurate quantification of coronary artery stenoses in the near future provided that further improvements in spatial and temporal resolution will be achieved.
