Study compares difference between MDCT and digital radiography in orthopedic patients

04.08.2006
Multi-detector computed tomography (MDCT) using high-quality 2D formatting is highly recommended as the primary imaging technique for the evaluation of bone healing, according to a study done by radiologists at the Medical University of Vienna in Vienna, Austria.

Forty-three patients with histories of fractures, arthrodesis (joint fusion) or spinal fusions who'd undergone MDCT and conventional radiography for the evaluation of bone healing were included in this study. Mutiplanar reconstructions and radiographs were analyzed by two musculoskeletal radiologists in consensus interpretation to determine bone healing.

According to the results, no evidence of bone bridging was shown in 14 patients, 23 patients showed evidence of partial fusion, and six patients showed complete fusion. In 27 patients (63%), MDCT and digital radiography were concordant with regard to the extent of bone healing, while in 16 patients (37%) the results were not concordant. In eight patients digital radiographs underestimated the extent of bone healing, while in another eight patients they overestimated the degree of fusion. "Most cases were dealing with bonehealing after spondylodiscitis, fractures or arthrodesis," said Christian R. Krestan, MD, lead author of the study. "However no scientific data were available concerning the value of MDCT in bone healing compared to radiographs, which had been used for decades in this indication," said Krestan.

"The results of this study have a considerable impact on orthopedic patients and lead to a substantial improvement in patient care," said Krestan. "The exact diagnosis or exclusion of bone healing provides a basis for decisions like mobilization or immobilization and even repeated surgery in these patients," he said.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
