Intracervical Foley catheter using and with out oxytocin regarding labour induction with Bishop score ≤3: an extra analysis.
As a marker of cellular proliferation, 18F-fluorothymidine (FLT) PET can detect the distribution of proliferating hematopoiesis and has an emerging role in the investigation of hematopoietic disorders. These images demonstrate the novel utility of 18F-FLT PET for imaging sites of extramedullary hematopoiesis (EMH) in a patient with Chuvash-type polycythemia and suggest a role for 18F-FLT PET in response assessment following radiotherapy. Further, the discordant response observed in the irradiated marrow and sites of EMH is a unique discovery, possibly suggesting the influence of the microenvironment favoring more rapid recovery of proliferative function within EMH sites.

68Ga-DOTATATE PET/CT is an important tool for imaging neuroendocrine tumors, including skeletal metastases. However, false-positive results can occur in inflammatory pathologies such as sacral insufficiency fracture. We report the case of a 47-year-old man who was diagnosed with a neuroendocrine tumor of the pancreas. 68Ga-DOTATATE PET/CT showed 68Ga-DOTATATE uptake at the right side of the sacrum. Afterward, MRI made the diagnosis of sacral insufficiency fracture.

Differentiated thyroid cancer with thyroglobulin elevation and negative iodine scintigraphy (TENIS) syndrome is a diagnostic and therapy dilemma. In this study, we present a case of TENIS with detectable metastases in the larynx and lung on the CT scan. Y27632 68Ga-fibroblast activation protein inhibitor (FAPI) PET/CT was performed for further detection of tumor recurrence and metastases, which showed intense 68Ga-FAPI activity in the metastatic lesions. To the best of our knowledge, this is the first case of TENIS presenting with FAPI-avid metastatic lesions, demonstrating its usefulness for localizing recurrent or metastatic lesions in patients with TENIS.

A 36-year-old asymptomatic woman was incidentally found to have a huge mass in the pancreas by ultrasound during routine health screening. The mass was suspected of neuroendocrine tumor or solid pseudopapillary tumor by subsequent abdominal CT. 18F-FDG and 68Ga-DOTATATE PET/MR were acquired for presurgical assessment of the tumor invasion and malignant potential, which revealed intense FDG uptake and mild DOTATATE uptake. The tumor was completely resected, and postsurgical pathology demonstrated pancreatoblastoma with neuroendocrine manifestations. This case showed the metabolic and biological features of pancreatoblastoma on the 18F-FDG and 68Ga-DOTATATE PET/MR.

A 40-year-old woman with a drug-resistant focal epilepsy underwent cerebral FDG PET in phase 1 presurgical epilepsy study. MRI essentially showed multiple periventricular nodular heterotopias. The stereoelectroencephalography coupled to MRI and FDG PET helped to define the anatomofunctional correlation of the epileptogenic zone network. This procedure brought to light 3 distinct patterns of FDG consumption, corresponding to different anatomoelectroclinical features. This pattern was already found in a previous FDG PET reflecting a "stable" permanent intralesional intercritical stereoelectroencephalography activity, an electrical "signature" of the lesion. Finally, functional imaging improved thermocoagulation in this patient and emphasized the use of FDG in drug-resistant epilepsy.
