The value of (18) F-FDG PET/CT in Diagnosis and Evaluation of Response to Treatment in Retroperitoneal Fibrosis

A 34-year-old male patient with abdominal pain and weight loss, without any known chronic disease, was referred to our clinic for Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scan for malignant etiology due to the detection of a mass lesion in abdominal computed tomography (CT). Sedimentation: 34 mm/hour, CRP: 8.3 mg/dl, PPD test and sputum ARB test were negative. Abdominal CT showed a mass lesion with soft tissue density extending from the i...

Fibroblast activation protein inhibitor (FAPi) positive tumour fraction on PET/CT correlates with Ki-67 in liver metastases of neuroendocrine tumours

Aim Gallium-68-labelled inhibitors of the fibroblast activation protein (FAPi) enable positron emission tomography/computed tomography (PET/CT) imaging of fibroblast activation. We evaluated if [68Ga]Ga-DATA5m.SA.FAPi PET/CT is related to Ki-67 as a marker of tumour aggressiveness in patients with liver metastases of NET.

Methods Thirteen patients with liver metastases of a histologically confirmed NET who underwent PET/CT with [68Ga]Ga-DATA5m.SA.FAPi, [18F]FDG and [68Ga]Ga-DOTA-TOC were retrospect...

Diagnosis and staging of hepatobiliary malignancies: Potential incremental value of (18)F-FDG-PET/MRI compared to MRI of the liver

Objective  The purpose of the study was to investigate the potential added value of18F-FDG-PET/MRI (functional information derived from PET) over standard diagnostic liver MRI (excellent soft tissue characterization) in diagnosing and staging suspected primary hepatobiliary malignancies including extrahepatic cholangiocarcinoma (ECC), intrahepatic cholangiocellular carcinoma (ICC) and gallbladder cancer (GBCA).

Methods  Twenty consecutive patients with suspected hepatobiliary malignancy were includ...

Morbidity and quality of life in patients with vulvar cancer after inguinal sentinel lymphadenectomy compared to radical inguinofemoral lymphadenectomy

Aim  Probability of survival of patients with vulvar cancer directly depends on the lymph node status. Surgery of lymph nodes can be performed as radical inguinofemoral lymphadenectomy or in cases with certain conditions as sentinel lymph node surgery. The aim of this study is to obtain an overview of the intervention-related morbidity and quality of life in patients with vulvar carcinoma after lymphadenectomy.

Methods  Quality of life and morbidity was compared between patients who underwent radic...

Value of PET imaging for radiation therapy *

This comprehensive review written by experts in their field gives an overview on the current status of incorporating positron emission tomography (PET) into radiation treatment planning. Moreover, it highlights ongoing studies for treatment individualisation and per-treatment tumour response monitoring for various primary tumours. Novel tracers and image analysis methods are discussed. The authors believe this contribution to be of crucial value for experts in the field as well as for policy mak...
