A temporal lobe factor in verb fluency.

Verb fluency requires self-sustained verb retrieval. The brain correlates of this task are virtually unknown. We investigated the relations between verb and noun (semantic) fluency and regional brain perfusion in subjects with varying degrees of cognitive decline, ranging from very mild subjective impairment to Alzheimer's disease (AD).

Integrin receptor imaging of breast cancer: a proof-of-concept study to evaluate 99mTc-NC100692.

Unlabelled: The present study was a proof-of-concept study to provide an initial indication of the efficacy and safety of imaging malignant breast tumors using (99m)Tc-NC100692. The agent is a small peptide with high affinity for integrin receptors that are upregulated and expressed preferentially on proliferating endothelial cells.

Methods: Sixteen patients with suggestive mammographic findings and 4 patients with benign lesions were included.

Imaging of regional lymph node metastases with 99mTc-depreotide in patients with lung cancer.

Purpose: The aim of this study was to evaluate the clinical usefulness of scintigraphy with 99mTc-depreotide in the assessment of loco-regional nodal spread in patients with suspected lung cancer in comparison with computed tomography (CT).

Methods: Eighty-six patients were investigated with single-photon emission computed tomography (SPECT) of the thorax after i.v.

99mTc-exametazime as a breast tumor-seeking agent: comparison with 99mTc-sestamibi.

Unlabelled: (99m)Tc-sestamibi is commonly used for mammoscintigraphy. Occasional uptake of (99m)Tc-exametazime in various tumors has been described. In this study, an intraindividual comparison of these 2 radiopharmaceuticals for mammoscintigraphy was made.

Indium-111-labelled donor-lymphocyte infusion by way of hepatic artery and radio-frequency ablation against liver metastases of renal and colon carcinoma after allogeneic hematopoietic stem-cell transplantation.

Background: In patients with metastatic solid cancer, antitumor effects occur after allogeneic stem-cell transplantation (SCT). However, this treatment is not as effective in the liver as against pulmonary and lymph-node metastases. To intensify the effect of donor-lymphocyte infusions (DLI) against liver metastases, intra-arterial (IA) cell injection by way of the hepatic artery (HA) can be used.

Accumulation of Tc-99m depreotide (NeoSpect) in axillary sweat glands.

Tc-99m depreotide (NeoSpect) is a radiolabeled somatostatin analog introduced recently for scintigraphic imaging of patients with lung cancer. Eighteen patients were examined 2 to 4 hours after administration of 740 MBq mCi Tc-99m depreotide. In 13 patients (72.

99mTc-sestamibi uptake and histological malignancy grade in invasive breast carcinoma.

The aim of this study was to investigate whether there is a correlation between (99m)Tc-sestamibi uptake and histological malignancy grade in breast carcinoma. Such a correlation could, prior to surgery and histopathological analysis, facilitate selection of patients who need adjuvant therapy. Ninety-six patients with mammographically determined lesions and/or a palpable tumour suspected for malignancy underwent (99m)Tc-sestamibi scintimammography prior to surgery.
