Navalón, C. Peña Radioiodine uptake in the thyroid tissue, metastasis of differentiated thyroid cancer (DTC), and in other tissues, depends on the expression of sodium-iodide symporter (NIS). Vascular permeability, effusions, inflammation, and other mechanisms may also play a role in the accumulation of radioactive iodine. A 63-year-old woman underwent radioiodine therapy, as well as a post-therapy ...

CONCLUSION: For the patient cohort studied, a wide range of absorbed doses would have been delivered for typical administration protocols in mCRPC. The methodology presented has potential use for emerging theragnostic agents. Advances in knowledge: The same patient cohort can receive a range of lesion absorbed doses from typical molecular radiotherapy treatments for patients with metastatic prostate cancer, highlighting the need to establish absorbed dose response relationships and to treat patients according to absorbed dose instead of using fixed administered activities.

BackgroundLung perfusion MRI after i.v. gadolinium (Gd) contrast administration is commonly based on spoiled gradient‐echo acquisitions, such as volume‐interpolated breath‐hold examinations (VIBE), suffering from low signal‐to‐noise in the parenchyma. PurposeTo investigate the lung signal enhancement ratio (SER) with ultra‐fast steady‐state free precession (ufSSFP) after Gd‐administration. Study TypeRetrospective. SubjectsTen subjects with healthy lungs; nine patients with pulmonary diseases (chronic obstructive pulmonary disease [COPD], lung cancer, pulmonary fibrosis, lung contusion). Field Strength/Seque...

Conclusion Four imaging procedures were evaluated from the perspective of a selected group of prostate cancer patients. NaF-PET/CT, choline-PET/CT, WB-MRI, and bone SPECT/CT are well accepted imaging methods, and most patients prefer NaF-PET/CT. PMID: 29313360 [PubMed - as supplied by publisher]

Authors: Nafisi Moghadam R, Amlelshahbaz AP, Namiranian N, Sobhan-Ardekani M, Emami-Meybodi M, Dehghan A, Rahmanian M, Razavi-Ratki SK Abstract Objective: Ultrasonography (US) and parathyroid scintigraphy (PS) with 99mTc-MIBI are common methods for preoperative localization of parathyroid adenomas but there discrepancies exist with regard to diagnostic accuracy. The aim of the study was to compare PS and US for localization of parathyroid adenoma with a systematic review and meta-analysis of the literature. Methods: Pub Med, Scopus (EMbase), Web of Science and the reference lists of all included studies were search...

Authors: Abadjian MZ, Edwards WB, Anderson CJ Abstract The tumor microenvironment consists of tumor, stromal, and immune cells, as well as extracellular milieu. Changes in numbers of these cell types and their environments have an impact on cancer growth and metastasis. Non-invasive imaging of aspects of the tumor microenvironment can provide important information on the aggressiveness of the cancer, whether or not it is metastatic, and can also help to determine early response to treatment. This chapter provides an overview on non-invasive in vivo imaging in humans and mouse models of various cell types and physio...
