The contemporary management of prostate cancer

CA: A Cancer Journal for Clinicians, EarlyView.
Abstract Prostate cancer is the most common cancer in two thirds of the world, with an expected doubling in both incidence and mortality in the next two decades. No strong environmental associations exist for the development of prostate cancer; therefore, lifestyle measures are unlikely to mitigate this increasing burden.

Development of a method for preparing octreotide derivative for diagnosis of neuroendocrine tumors

Бюллетень сибирской медицины, 2019
Currently the development of technologies for labeling somatostatin with technetium-99m for diagnosing radionuclide neuroendocrine tumors is under way. Somatostatin analogues are binded with technetium99m only by the preliminary addition of a chelating ...

Optical surface information‐based respiratory phase‐sorting and motion‐incorporated reconstruction for SPECT imaging

Medical Physics, Volume 52, Issue 6, Page 4330-4340, June 2025.
Abstract Background Respiratory motion during the single photon emission computed tomography (SPECT) acquisition can cause blurring artifacts in the reconstructed images, leading to inaccurate estimates for activity and absorbed doses. Purpose To address the impact of respiratory motion, we utilized a new optical surface imaging (OSI) system to extract

Complete improvement in a patient with multiple irreversible defects of the left ventricle on 99m technetium-sestamibi SPECT after percutaneous coronary intervention. [PDF]

, 2012
99mTc-sestamibi has been investigated as a potential viability marker; initial studies have shown good concordance between 201Tl and 99mTc-sestamibi activities in both viable and nonviable myocardium.

Development and Study of {99m}Tc-1-Thio-D-glucose for Visualization of Malignant Tumors [PDF]

, 2004
The preclinical studies of {99m}Tc-1-Thio-D-glucose, a new tumor-seeking agent based on technetium-99mlabeled glucose derivative, were conducted, and the feasibility of using this radiopharmaceutical for tumor visualization was studied.

Hybrid method for estimating lung ventilation from CT by combining intensity and motion information

Medical Physics, Volume 52, Issue 6, Page 4528-4539, June 2025.
Abstract Background Functional lung imaging modalities allow for capturing regional lung ventilation information. Computed Tomography based ventilation imaging (CTVI) has been proposed as a surrogate modality that relies on time‐resolved anatomical data and image processing. However, generating accurate ventilation maps using solely computed tomography

Scintigraphy with 99mTc(V)-DMSA in monitoring patients with inflammatory bowel disease [PDF]

, 2013
The clinical significance of pentavalent technetium-99m dimercaptosuccinic acid (99mTc(V)-DMSA) scintigraphy in diagnosing inflammatory bowel disease (IBD) has not yet been fully elucidated. The aim of this prospective paper was to study the above.

How does study quality affect the results of a diagnostic meta-analysis? [PDF]

, 2005
Background: The use of systematic literature review to inform evidence based practice in diagnostics is rapidly expanding. Although the primary diagnostic literature is extensive, studies are often of low methodological quality or poorly reported.
