Correction of artefacts associated with large area EBSD

Artefacts associated with a cryoglobulin.

A 70 year old man is described in whom the presence of a cryoglobulin caused a number of unusual laboratory features which were not recognized as being due to a cryoglobulin initially. Pseudoleucocytosis has been recognized in the past. However, the intracytoplasmic inclusion bodies have only rarely been described. The curious appearance of the ESR has not previously been described.

Reduction of Collimator Correction Artefacts with Bayesian Reconstruction in Spect

Poor resolution of single photon emission computed tomography (SPECT) has degraded its use in clinical practice. Collimator correction has been shown to improve the reconstructed resolution, but the correction can generate ringing artefacts, which lower image quality. This paper investigates whether Bayesian reconstruction methods could reduce these artefacts. We have applied and tested three B...

Anaplastic Large Cell Lymphoma Associated With Breast Implants

A forty two years old woman with a history of bilateral breast augmentation for cosmetic reasons was presented for poor healing of the surgical site. Tissue and periprosthetic fluid were removed from the wound site revealing an atypical lymphoid infiltrate. Subsequently the patient developed axillary lymph adenopathy. Excisional biopsy was performed. Flow cytometry was non-diagnostic. She conti...

Correction of Motion Artefacts in Magnetic Resonance Imaging

Magnetic Resonance Imaging (MRI) can provide high quality images exhibiting good soft tissue contrast and without the use of potentially harmful ionising radiation. The process of MR image formation is inherently slow compared to many physiological processes and this can lead to image artefacts such as a blurring and ghosting. The aim of the project was to correct for motion artefacts. MR data ...
