In patients with a patent foramen ovale, use of air filters during intravenous infusions is common, but they are not compatible with power injection. Therefore we aimed to assess the incidence of paradoxical air embolism on CT of the chest and brain following contrast material injection through a power injector ...

Infantile hepatic hemangioma is the most common benign liver tumor during infancy. Prompt diagnosis and timely institution of therapy are of utmost importance. Magnetic resonance imaging (MRI) plays a key role in the correct diagnosis and monitoring of treatment. We report on a 15-week-old girl with multifocal infantile hemangiomas of ...

BACKGROUND AND PURPOSE: HDR brachytherapy is used as a conformal boost for treating prostate cancer. Given the large doses delivered, it is critical that the volume treated matches that planned. Our outpatient protocol comprises two 9Gy fractions, two weeks apart. We prospectively assessed catheter displacement between CT planning and treatment ...

We report a case of a 59-year-old man with testicular germ cell tumor who showed new hypermetabolic lesions at the left axillary lymph nodes on a post-treatment positron emission tomography-computed tomography (PET-CT) scan. The hypermetabolic lesions were found to be caused by an influenza vaccination 10 days prior to the ...

PURPOSE: Patients with locally advanced cervical cancer (LACC) are usually treated with concurrent chemoradiotherapy. Extended-field chemoradiotherapy is indicated in case of para-aortic node involvement at initial assessment. 18-Fluoro-2-deoxy-D: -glucose positron emission tomography/computed tomography (18-FDG PET/CT) is currently considered to be the most accurate method of detection of node or distant ...

Mandibular para-radicular third molar radiolucencies (MPRs) were first described in 2004 by Bohay et al (Bohay RN, Mara TW, Sawula KW, Lapointe HJ. A preliminary radiographic study of mandibular para-radicular third molar radiolucencies. Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2004; 98: 97-101) as a well-defined oval radiolucency ...

We report a case of syphilis with pulmonary involvement. Chest CT scan and (18)F-fluorodeoxyglucose (FDG) PET/CT showed multiple pulmonary nodules mimicking pulmonary hematogenous metastases. This was confirmed on follow-up images that showed therapeutic response to penicillin.

To apply single-photon emission computed tomography (SPECT) in combination with computed tomography (CT) for preoperative identification of sentinel lymph nodes (SNs) and to investigate surgical feasibility and safety of intraoperative sampling. A retrospective combined interim analysis of 20 patients from two prospective trials who underwent injection of 99mTc-nanocolloid into the ...

Failure to detect metastasis to para-aortic nodes in patients with locally advanced cervical cancer leads to suboptimal treatment. No previous studies have prospectively compared positron emission tomography (PET)/computed tomography (CT) with laparoscopic extraperitoneal staging in the evaluation of para-aortic lymph nodes. Sixty-five patients were enrolled; 60 were available for analysis. ...

BACKGROUND:: Failure to detect metastasis to para-aortic nodes in patients with locally advanced cervical cancer leads to suboptimal treatment. No previous studies have prospectively compared positron emission tomography (PET)/computed tomography (CT) with laparoscopic extraperitoneal staging in the evaluation of para-aortic lymph nodes. METHODS:: Sixty-five patients were enrolled; 60 were available ...

A 24-year-old man with tuberculosis meningitis developed acute paraplegia and sensory disturbances 5 weeks after receiving conventional antituberculous therapy. Magnetic resonance imaging revealed an intradural extramedullary long segmental mass mimicking en plaque meningioma at the T2-T6 vertebrae levels. Prompt surgical decompression was performed. A histology examination of the mass revealed ...

BACKGROUND: Since the internal structure of a tablet can be measured without destruction of the sample by X-ray computed tomography (CT), it could be applied to quality control of tablets during the manufacturing process. AIM: A novel, fast, noninvasive tablet observation method was developed to evaluate the internal structure of ...

Leider ist uns in der Ausgabe 6/2008 "Antitussiva/Expektorantien" in dem Artikel "Medizinisch-chemische Aspekte - Antitussiva und Expektorantien" in Abb. 2, Seite 463, ein Formelfehler unterlaufen. Die Abbildung enthält die Struktur von Levomethorphan statt der des beschriebenen antitussiven Dextromethorphans. Zur Sicherheit haben wir beide Strukturen hier nochmals aufgeführt (Abb.).Die Autoren.

During curative cancer surgery, magnetic retraction could offer advantages over retraction by graspers because of reduced tissue trauma and with the potential for noncontact retraction. To realize magnetic retraction, magnetic fluid was injected into harvested porcine stomachs and an external permanent magnet was used to retract the ferromagnetized tissue. The ...

The standardization of diagnostic immunofluorescence is a complex problem because diagnostic results are greatly influenced by interacting factors, such as the equipment, materials, and techniques for expressing and recording fluorescence. Furthermore, the characteristics of immunofluorescence reagents depend on how they are manufactured and used. The adoption of stable reference preparations ...
