Computed DWI MRI Results in Superior Capability for N-Stage Assessment of Non-Small Cell Lung Cancer Than That of Actual DWI, STIR Imaging, and FDG-PET/CT.

J Magn Reson Imaging 2022 Jun 26. Epub 2022 Jun 26.

Department of Radiology, Fujita Health University School of Medicine, Toyoake, Japan.

Background: Computed diffusion-weighted imaging (cDWI) is a mathematical computation technique that generates DWIs for any b-value by using actual DWI (aDWI) data with at least two different b-values and may improve differentiation of metastatic from nonmetastatic lymph nodes.

Purpose: To determine the appropriate b-value for cDWI to achieve a better diagnostic capability for lymph node staging (N-staging) in non-small cell lung cancer (NSCLC) patients compared to aDWI, short inversion time (TI) inversion recovery (STIR) imaging, or positron emission tomography with 2-[fluorine-18] fluoro-2-deoxy-d-glucose combined with computed tomography (FDG-PET/CT).

New PET Tracers: Current Knowledge and Perspectives in Lung Cancer.

Semin Nucl Med 2022 Jun 22. Epub 2022 Jun 22.

Department of Clinical Physiology and Nuclear Medicine, Rigshospitalet Copehagen University Hospital, Copenhagen, Denmark.

PET/CT with the tracer 2-[F]fluoro-2-deoxy-D-glucose ([F]FDG) has improved diagnostic imaging in cancer and is routinely used for diagnosing, staging and treatment planning in lung cancer patients. However, pitfalls of [F]FDG-PET/CT limit the use in specific settings. Additionally, lung cancer is still the leading cause of cancer associated death and has high risk of recurrence after curative treatment. Read More

PET/MR Imaging of a Lung Metastasis Model of Clear Cell Renal Cell Carcinoma with (2S,4R)-4-[F]Fluoroglutamine.

Mol Imaging Biol 2022 Jun 22. Epub 2022 Jun 22.

Department of Urology, MD Anderson Cancer Center, 1515 Holcombe Blvd, Houston, TX, 77030, USA.

Purpose: Metabolic reprogramming plays an important role in the tumorigenesis of clear cell renal cell carcinoma (ccRCC). Currently, positron emission tomography (PET) reporters are not used clinically to visualize altered glutamine metabolism in ccRCC, which greatly hinders detection, staging, and real-time therapeutic assessment. We sought to determine if (2S,4R)-4-[F]fluoroglutamine ([F]FGln) could be used to interrogate altered glutamine metabolism in ccRCC lesions in the lung. Read More

Added Value of Respiratory Gating in Positron Emission Tomography for the Clinical Management of Lung Cancer Patients.

Semin Nucl Med 2022 May 25. Epub 2022 May 25.

Department of Radiology, Leiden University Medical Center, Leiden, The Netherlands.

Positron emission tomography (PET) is an important imaging modality for personalizing clinical management of patients with lung cancer. In this regard, PET imaging is essential for adequate clinical staging and monitoring of treatment response in patients with lung cancer. The key advantage of PET over other radiological imaging modalities is its high sensitivity for the detection of pulmonary lesions, normal-sized metastatic hilar and/or mediastinal lymph nodes, and distant metastases.

Rodney J Hicks

Semin Nucl Med 2022 May 24. Epub 2022 May 24.

Department of Medicine, St Vincent's Medical School, University of Melbourne, Melbourne Academic Centre for Health, University of Melbourne Centre for Cancer Research, Victorian Comprehensive Cancer Centre, Central Clinical School, Alfred Hospital, Monash University, Melbourne VIC, Australia. Electronic address:

The diagnosis, staging and therapeutic monitoring of lung cancer were amongst the first applications for which the utility of FDG PET was documented and FDG PET/CT is now a routine diagnostic tool for clinical decision-making. As well as having high sensitivity for detection of disease sites, which provides critical information about stage, the intensity of uptake provides deeper biological characterization, while the burden of disease also has potential clinical significance. These disease characteristics can easily be quantified on delayed whole-body imaging as the maximum standardized uptake value (SUV) and metabolic tumor volume (MTV), respectively. Read More

From the Department of Abdominal Imaging, The University of Texas MD Anderson Cancer Center, 1400 Pressler St, Houston, TX 77030 (A.W., M.B., B.R.K., K.M.E.); Department of Radiology, Mayo Clinic, Jacksonville, Fla (M.D., C.W.B.); Department of Radiology, The University of Texas Health Science Center at Houston, Tex (J.G.); Department of Radiology, University of Wisconsin School of Medicine and Public Health, Madison, Wis (P.J.P., M.G.L.); Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Mo (V.M.M.); and Department of Laboratory Medicine and Pathology, Mayo Clinic, Scottsdale, Ariz (L.C.).

Extraskeletal Ewing sarcoma (EES) is a rare subtype in the Ewing sarcoma family of tumors (ESFT), which also includes Ewing sarcoma of bone (ESB) and, more recently, primitive neuroectodermal tumors. Although these tumors often have different manifestations, they are grouped on the basis of common genetic translocation and diagnosis from specific molecular and immunohistochemical features. While the large majority of ESFT cases occur in children and in bones, approximately 25% originate outside the skeleton as EES. Read More
