Multimodal tilmanocept for preoperative imaging and fluorescence-guided surgery of porcine lateral pelvic sentinel lymph nodes

Ryotaro Ogawa, Junichiro Kawamura, Edward Tom Ashworth, Soo Bin Park et autres

The management of lateral pelvic lymph nodes in locally advanced lower rectal cancer remains controversial. The sentinel lymph node (SLN) mapping can potentially enhance patient selection for lateral pelvic lymph node dissection. The current mapping agent, indocyanine green dye cannot be externally …

Effects of Cigarette Smoking and 3‐Day Smoking Abstinence on Translocator Protein 18 kDa Availability: A [18F]FEPPA Positron Emission Tomography Study

Arthur L. Brody, Andre Y. Sanavi, Renee Beverly‐Aylwin, Natalie Guggino et autres

ABSTRACT With the many negative health consequences of cigarette smoking, quitting is known to improve health in multiple domains. Using positron emission tomography/computed tomography (PET/CT) scanning, our group previously demonstrated that smokers have lower levels than nonsmokers of translocator protein binding both …

Cigarette smoking is associated with reduced neuroinflammation and better cognitive control in people living with HIV

Arthur L. Brody, Anna K. Mischel, Andre Y. Sanavi, Alvin Seng Cheong Wong et autres

People living with HIV (HIV+) are roughly twice as likely to smoke cigarettes (Smok+) as the general population. With the advent of effective antiretroviral therapies, it is increasingly important to understand the effects of chronic HIV infection and cigarette smoking on brain …

Multidisciplinary Approach to Chronic Thromboembolic Pulmonary Hypertension: Role of Radiologists

Lewis D. Hahn, Demosthenes G. Papamatheakis, Timothy M. Fernandes, David S. Poch et autres

Management of chronic thromboembolic pulmonary hypertension (CTEPH) should be determined by a multidisciplinary team, ideally at a specialized CTEPH referral center. Radiologists contribute to this multidisciplinary process by helping to confirm the diagnosis of CTEPH and delineating the extent of disease, both …

Improved Prognosis of Treatment Failure in Cervical Cancer with Nontumor PET/CT Radiomics

Tahir Yusufaly, Jingjing Zou, Tyler J. Nelson, Casey W. Williamson et autres

Background: Radiomics has been applied to predict recurrence in several disease sites, but current approaches are typically restricted to analyzing tumor features, neglecting non-tumor information in the rest of the body. The purpose of this work was to develop and validate a …

Assessing CAR T-Cell Therapy Response Using Genome-Wide Sequencing of Cell-Free DNA in Patients With B-Cell Lymphomas

Aaron Michael Goodman, Kimberly A. Holden, Ah‐Reum Jeong, Lisa Kim et autres

Methods that enable monitoring of therapeutic efficacy of autologous chimeric antigen receptor (CAR) T-cell therapy will be clinically useful. The aim of this study is to demonstrate the feasibility of blood-derived cell-free DNA (cfDNA) to predict CAR T-cell therapy response in patients …

MicroPET evidence for a hypersensitive neuroinflammatory profile of gp120 mouse model of HIV

Jared W. Young, Christopher V. Barback, Louise A. Stolz, Stephanie Mary Groman et autres

Abstract Despite increased survivability for people living with HIV (PLWH), HIV-related cognitive and behavioral abnormalities persist. Determining the biological mechanism(s) underlying these abnormalities is critical to minimize the long-term impact of HIV. Human positron emission tomography (PET) studies reveal that PLWH exhibit …

Risk Stratification in Diffuse Large B Cell Lymphoma: A Review of Novel FDG PET/CT Imaging and Liquid Biopsy Biomarkers and Suggestions for Future Directions to Improve Prognostic Accuracy

Ryan Thompson, Amin Haghighat Jahromi, Aaron Michael Goodman, Carl K. Hoh et autres

2026 Introduction: Diffuse large B cell lymphoma (DLBCL) is the most common form of lymphoid cancer, accounting for up to 25-30% of non-Hodgkin lymphoma. Current first-line treatment regimens, which include rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) are effective in 60-70% of …

FDG embolism mimicking lung metastasis

Amin Haghighat Jahromi, Carl K. Hoh

2-[18F]-FDG embolism artifact is a PET pitfall that may cause misinterpretation as lung metastasis. This rare phenomenon results from clumping of the radiotracer with platelet aggregates during intravenous administration. It should be considered, especially if there is no corroborating anatomic correlate for …
