Prostate cancer is the most frequently occurring cancer in men. Considerable improvements have been
implemented in the diagnosis with the Magnetic Resonance Imaging (MRI) technique, and with nuclear
medicine techniques of scintigraphy and Positron Emission Tomography (PET). Unfortunately, the presently
used standard clinical nuclear medicine imagers for single gamma imaging (gamma...

Dedicated high resolution detectors are needed for detection of small tumors by
molecular imaging with radionuclides. Absorptive collimation typically used for
imaging single photon emitters, results in a strong reduction in efficiency. System
based on electronic collimation is offering higher efficiency but is complex and
expensive. For these reasons, the simulations and measurements...

The Clear-PEM scanner for positron emission mammography under development is
described. The detector is based on pixelized LYSO crystals optically coupled to
avalanche photodiodes (APD) and readout by a fast low-noise electronic system. A
dedicated digital trigger and data acquisition system is used for on-line selection
of coincidence events with high efficiency, large bandwidth and...

High resolution PET imaging is now a well established technique not only for small
animal, but also for human brain studies. The ECAT HRRT brain PET scanner (Siemens
Molecular Imaging) is characterized by an effective isotropic spatial resolution of
2.5 mm, about a factor of 2 better than for state-of-the-art whole-body clinical PET
scanners. Although the absolute sensitivity of the HRRT...

Fibromyalgia (FM) syndrome is a chronic pain illness characterized by widespread
musculoskeletal aches, pain and stiffness, soft tissue tenderness, general fatigue
and sleep disturbances, without clinically demonstrable peripheral nociceptive
cause. If a psychogenic trouble has been initially postulated, recent fMRI studies
clearly demonstrated a global dysfunction of central pain...

The use of external positron emitting sources or single photon emitting sources at
energies similar to annihilation photons seems to give acceptable results
permitting the quantification of PET data. The attenuation correction based on CT
data generates artefacts around metallic prostheses, after use of contrast media
and in the pulmonary region near calcifications and on dense...

Internal targeted radiotherapy consists in the in situ irradiation of tumour cells
using an appropriate radiolabelled agent. Such an agent should be sufficiently
tumour-specific in order to accumulate and be retained for a long time in the
tumour, while its elimination from normal tissues should occur quickly. Such an
approach has already proved to be efficient for the treatment of...

Purpose: To test the feasibility of FDG based PET/CT data on target volume
delineation in radiotherapy treatment planning of NSCLC patients, and impact of
these outlined biological target volumes (BTV) for IMRT treatment.
Materials and methods: Patient diagnosed with non-operable NSCLC in the right upper
lobe had a 3D conformal planning based on CT data with our hypo-fractionated...

Several years ago we presented the idea that PET resolution better than the
intrinsic range of the positron at good sensitivity was achievable by placing a high
resolution detector—ideally taking the form of a small diameter ring—within the bore
of a conventional PET detector ring (J. Nucl. Med. Supp. 2000, 41(5):20P, 2001, 42
(5):55P, 102P). While we examined constructing the inner...

Background. Whole body exercise thallium scintigraphy can detect silent or
symptomatic PAD. Whether exercise thallium perfusion muscular asymmetry in the legs
has prognostic value is unknown.
Methods and Results –Three hundred fifty-eight consecutive patients (mean age
58.8±10.2 year; coronary artery disease, 202/358; 56.4 %) were prospectively
followed after thallium 201...

Aim. Radio-isotope guidance is useful in several fields of surgery, such as
sentinel node biopsy, parathyroid adenoma and of some neuroendocrine tumours,
withdrawal of laterocervical lymph nodes invaded by thyroid cancer.
Radioguided surgery (RGS) is generally performed with a gamma probe (GP) providing
an acoustic signal proportional to the detected activity. The Imaging Probe (IP) is...
