Torso Crowds.

We present a novel dense crowd simulation method. In real crowds of high density, people manoeuvring the crowd need to twist their torso to pass between others. Our proposed method does not use the traditional disc-shaped agent, but instead employs capsule-shaped agents, which enables us to plan such torso orientations.

Radioembolization of the spleen: a revisited approach for the treatment of malignant lymphomatous splenomegaly.

Intraarterial administration of (90)Y microspheres to the spleen in patients with malignant lymphoma was mentioned once in the literature in 1973. This case study illustrates the potential indication of selective internal radiotherapy in a heavily pretreated patient with highly refractory disease with a marginal zone lymphoma in leukemic phase and symptomatic splenomegaly. We describe the clinical course of disease; the biological and clinical response to the treatment after radioembolization; and simulation and dosimetry by multimodal imaging via single-photon emission computed tomography and computed tomography.

Progress in magnetic resonance imaging of brain tumours.

Purpose Of Review: Advances in magnetic resonance based techniques have yielded improvements in both high-resolution anatomical imaging and methods to evaluate physiology and function. This review focuses on recent developments in these techniques as applied to pretreatment staging and post-treatment evaluation of brain tumours.

Recent Findings: High-resolution spectroscopic imaging may contribute to pre-therapeutic grading and characterization of gliomas, as can diffusion techniques.
