Established imaging modalities for the characterization of liver tumors are computed tomography (CT), magnetical resonance (MR) imaging, sonography, and hepatobiliary scintigraphy. In some cases, their results may be inconclusive or certain examinations not possible due to contraindications. Positron emission tomography (PET)/CT has the capability of dynamic imaging with high temporal resolution. With radiolabeled tri-alkoxysalicyl-1,4-diazepan-6-amine (TAoS-DAZA) tracers, imaging of liver perfu...

Conventional ultrasound (US) is time-consuming, and results are subjected to high interobserver variability. In this study, the reliability of a novel thyroid US cine loop standard operating procedure (SOP) applied by non-physicians (Medical Technical Assistant, MTA) is investigated. Thirty-three consecutive patients (22 females, 11 males) were enrolled. Patients underwent conventional thyroid US performed by a nuclear medicine physician and additional MTA US cine loop according to a local SOP t...

This chapter is about initial experiences regarding the feasibility and applicability of quasi-integrated freehand (fh) single-photon emission computed tomography (SPECT)/ultrasonography (US) fusion imaging in patients undergoing sentinel lymph node (SLN) imaging or in patients with thyroid disease. The principles of radioguided surgery can be applied to this technology. The successful and emerging concept of hybrid imaging is applied to US imaging, resulting in a tool that combines the delivery...

Purpose: To report an initial experience regarding the feasibility and applicability of quasi-integrated freehand single photon emission computed tomography (SPECT)/ultrasonography (US) fusion imaging in patients with thyroid disease. Materials and Methods: Local ethics committee approval was obtained, and 34 patients were examined after giving written informed consent. After intravenous application of 75 MBq of technetium 99m pertechnetate, freehand three-dimensional SPECT was performed. Data w...

A 57-year-old previously healthy woman presented with a history of fever for 6 months, weight loss of 20 kg, and dry cough. Ambulatory antibiotic treatment failed to improve her symptoms. On physical examination (blood pressure, 100/60 mm Hg; heart rate, 64 bpm), she appeared tired, was pale, but was not in acute distress. Lungs and heart appeared normal on auscultation. The abdomen was soft and not tender with normal bowel sounds. The neurological examination was unremarkable. Abnormal laborato...
