PURPOSE The aim of this study was to assess the diagnostic performance of simultaneous whole-body Ga-DOTANOC PET/MRI compared with Ga-DOTANOC PET/CT for detection of distant metastatic disease in patients with well-differentiated neuroendocrine tumors (NETs). METHODS Patients with histologically proven, well-differentiated NET (G1 or G2) were included in this prospective, institutional review...

Prostate-specific membrane antigen (PSMA) is a promising target in prostate cancer. Recently, we started the first-in-human treatment with an α-radionuclide–labeled PSMA ligand. Although the case series is still ongoing, we here report in advance about two patients in highly challenging clinical situations who showed a complete response to 225AcPSMA-617 therapy. Methods: 68Ga-PSMA-11 PET/CT val...

We quantified pulmonary vascular permeability with positron emission tomography (PET) and gallium-68-(68Ga) labeled transferrin. Six dogs with oleic acid-induced lung injury confined to the left lower lobe, two normal human volunteers, and two patients with the adult respiratory distress syndrome (ARDS) were evaluated. Lung tissue-activity measurements were obtained from sequential 1-5 min PET ...

relapse at low PSA values <1 ng ml−1, the obtained detection rates of 99mTc-labeled PSMA-SPECT/CT are lower than those reported by 68Ga-PSMA PET/CT imaging.1 This is in line with our experiences in early recurrent prostate cancer patients and low PSA values investigated with PSMA tracers for SPECT/CT imaging.3 Although very useful for PSMA-radioguided surgery,4,5 111 In-labeled PSMA I&T (or 99m...

CONTEXT Inherited and sporadic medullary thyroid cancer (MTC) is an uncommon and medically challenging malignancy. Even if the extent of initial surgery is deemed adequate, the recurrence rate remains high, up to 50% in most series. Measurement of serum calcitonin is important in the follow-up of patients with MTC, and reliably reflects the existence of the disease. EVIDENCE ACQUISITION There...

Neuroectodermal tumours are characterized by aberrant processing of disialogangliosides concomitant with high expression of GD2 or GD3 on cell surfaces. Antibodies targeting GD2 are already in clinical use for therapy of neuroblastoma, a solid tumour of early childhood. Here, we set out to identify peptides with high affinity to human disialoganglioside GD2. To this end, we performed a combined...
