Radiation therapy has emerged as a useful alternative therapy for patients with early-stage, non-resectable lung cancer. In patients whose malignancies are difficult to localize on computed tomography imaging, such therapy becomes difficult. Fiducial markers are frequently placed in peripheral pulmonary lesions to assist radiation therapy. Although placement of markers under linear endobronchial ultrasonography within mediastinal and hilar lymph nodes has been reported, no strategy has been described to assist radiotherapy of purely endobronchial tumors...

Ultrasound contrast agents (UCA) represented by gas-filled microbubble, can provide simultaneous and co-localized enhancement on image contrast to help disease diagnosis by highlighting tissue borders. Nowadays, Some UCAs (e.g. Levovist®, Optison®, Definity®, and Sonovue®) are commercially available, and have been clinically utilized for enhanced ultrasonography in the US, Canada, Europe, Asia and so on. However, their large diameters (1~10 μm) mainly hinder more precise and deeper applications in the imaging of capillary-abundant organs or tissues (e...

Juvenile idiopathic arthritis (JIA) and osteoarticular infection can cause nonspecific articular and periarticular complaints in children. Although contrast material-enhanced magnetic resonance imaging is the reference standard imaging modality, musculoskeletal ultrasonography (US) is emerging as an important adjunct imaging modality that can provide valuable information relatively quickly without use of radiation or the need for sedation. However, diagnostic accuracy requires a systemic approach, familiarity with various US techniques, and an understanding of maturation-related changes...

In their introduction, Gungor et al described ultrasound as a technique for evaluation of patients with low prior probability of acute appendicitis. This testing protocol for appendicitis is being proposed to challenge and perhaps replace the current standard of care for imaging, CT scanning. Specificity of CT scanning is reported in the range of 92-98% and CT is generally felt to be more accurate than ultrasonography The finding of 95.8% specificity for their method appears competitive and may be arithmetically correct but is seriously flawed...

We describe the case of a 55-year old women admitted at night to the emergency department (ED), complaining for acute abdominal pain lasting for nearly 5 hours. A first blood testing, performed immediately after admission, revealed mild anaemia. A second blood sample, drawn two hours after admission, revealed a considerable decrease of haemoglobin, haematocrit, total white blood cell and platelet counts (between 10-15% reduction). Abdominal ultrasonography was normal and the patient had no signs or symptoms of internal or external haemorrhage...

Isolated tubal torsion -a rare cause of acute abdomen in children-is usually difficult to diagnose because of non-specific findings. Surgical salphingectomy is required in delayed diagnosis in most cases. Three sexual inactive adolescents diagnosed in isolated tubal torsion (ITT) were discussed for its diagnostic features and surgical management. Laboratory tests and radiological studies including ultrasonography (US), color doppler ultrasound were performed in all patients after evaluation for acute lower abdominal pain in emergency department and they underwent surgical intervention with laparotomy (n:2) and laparoscopy (n:1)...

To demonstrate surgical techniques utilized during uterine-sparing laparoscopic resections of accessory cavitated uterine masses (ACUM) BACKGROUND: ACUM represent a rare uterine entity observed in premenopausal women suffering from dysmenorrhea and recurrent pelvic pain. The diagnosis is made when an isolated extra-cavitated uterine mass is resected from an otherwise normal appearing uterus with unremarkable endometrial lumen and adnexal structures. Pathologic confirmation requires an accessory cavity lined with endometrial epithelium (and corresponding glands and stroma) filled with chocolate-brown fluid...
