Rituximab in combination with chemotherapy for the treatment of chronic lymphocytic leukaemia in clinical practice.

Objectives: This study was conducted to investigate the real-world effectiveness and tolerability of rituximab-containing chemoimmunotherapies, which have become the standard of care for chronic lymphocytic leukaemia (CLL), particularly for physically fit patients. Furthermore, current treatment patterns in clinical practice were documented, and an unselected real-life population was compared with older, comorbid patients.

Methods: Prospective, multicentre, observational study with rituximab-containing chemoimmunotherapy in CLL patients.

Diagnostic accuracy of 123I-FP-CIT SPECT in possible dementia with Lewy bodies.

Background: (123)I-FP-CIT SPECT (single photon emission computed tomography) can help in the differential diagnosis of probable dementia with Lewy bodies (Lewy body dementia) and Alzheimer's disease.

Aims: Our aim was to determine the accuracy of (123)I-FP-CIT SPECT in diagnosing people with possible dementia with Lewy bodies.

Method: We undertook a 12-month follow-up of 325 individuals with probable or possible Lewy body or non-Lewy body dementia who had previously undergone (123)I-FP-CIT SPECT.

Parkinson's disease is overdiagnosed clinically at baseline in diagnostically uncertain cases: a 3-year European multicenter study with repeat [123I]FP-CIT SPECT.

Overdiagnosis of Parkinson's disease (PD) is suggested by specialist review of community diagnosis, and in postmortem studies. In specialist centers 4 to 15% of patients entered into clinical trials as early PD do not have functional imaging support for a PD diagnosis. In a European multicenter, prospective, longitudinal study, we compared clinical diagnosis with functional SPECT imaging using [123I]FP-CIT (DaTSCAN, GE Healthcare).

MR-IMPACT: comparison of perfusion-cardiac magnetic resonance with single-photon emission computed tomography for the detection of coronary artery disease in a multicentre, multivendor, randomized trial.

Aims: To determine in a multicentre, multivendor trial the diagnostic performance for perfusion-cardiac magnetic resonance (perfusion-CMR) in comparison with coronary X-ray angiography (CXA) and single-photon emission computed tomography (SPECT).

Methods And Results: Of 241 eligible patients from 18 centres, 234 were randomly dosed with 0.01, 0.

Characterization of liver lesions with mangafodipir trisodium-enhanced MR imaging: multicenter study comparing MR and dual-phase spiral CT.

Purpose: To evaluate whether mangafodipir trisodium (Mn-DPDP)-enhanced magnetic resonance (MR) imaging surpasses dual-phase spiral computed tomography (CT) in differentiating focal liver lesions.

Materials And Methods: One hundred forty-five patients who had or were suspected of having focal liver lesions were included in a multicenter study and underwent dual-phase spiral CT and enhanced MR imaging. Image interpretations performed by independent experienced radiologists were compared with the final diagnosis that was based on all available clinical information (including histopathologic findings in 77 patients) and that was determined with consensus.
