Dosimetric Considerations in Radioimmunotherapy and Systemic Radionuclide Therapies: A Review

World Journal of Nuclear Medicine, 2011
Radiopharmaceutical therapy, once touted as the "magic bullet" in radiation oncology, is increasingly being used in the treatment of a variety of malignancies; albeit in later disease stages. With ever-increasing public and medical awareness of radiation

Size‐specific dose estimates calculated using patient size measurements from scanned projection radiograph in high‐resolution chest computed tomography

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 85-92, March 2025.
This study established that patient's lateral width measurements made from scanned projection radiograph (SPR) is an overestimate compared to those measured from tomographic slices by about 10%. Size‐specific dose estimates (SSDE) calculated using lateral width measured from SPR correlates well with SSDE calculated using water equivalent diameter of ...

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Molecular theranostics: principles, challenges and controversies

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 156-164, March 2025.
Molecular theranostics offers a powerful tool to drive precision medicine in nuclear oncology. While theranostics is not a new principle in nuclear medicine, recent advances in instrumentation and radiopharmacy have driven a reinvigoration and a broader suite of applications.

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.
In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...

The Prognostic Value of EDRIC and Its Association With Radiation‐Induced Lymphopenia in Patients With Esophageal Cancer Undergoing Radical Radiotherapy: A Single‐Center Chinese Study

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the predictive value of the estimated dose of radiation to immune cells (EDRIC) in patients with esophageal cancer receiving radical radiotherapy. We retrospectively reviewed the data of patients with esophageal cancer who underwent definitive radiotherapy at our institution.

Laparoscopic Methylene Blue Photodynamic Therapy for Intraabdominal Infection: A Preclinical Feasibility Study in a Rabbit Model of Perforated Appendicitis

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Perforated appendicitis commonly results in intra‐abdominal infection requiring prolonged antibiotic therapy. Intraoperative antimicrobial adjuncts are limited, and photodynamic therapy (PDT) may provide a targeted, resistance‐independent approach.
