Abstract Background Preoperative computed tomography (CT)-guided coil localization (CL) is commonly used to facilitate video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection (WR) of pulmonary nodules (PNs). When a scapular-blocked PN (SBPN) localized, the trans-scapular CL (TSCL) performed. In this study, we investigated safety, feasibility, and clinical efficacy preopera...

OBJECTIVE It is important to identify and save the normal parathyroid glands during head and neck surgery because of their role in regulating the blood calcium level, yet it is often difficult to localize normal parathyroid glands during surgery. Fluorescence-guided parathyroidectomy in patients with hyperparathyroidism has already proved useful. However, there are few reports of fluorescence-g...

Background: Retained appendicolith related abscess formation is rare and carries challenging management options. We describe a unique case of a patient who presented with right upper quadrant pain tenderness that is clinically mimicking acute cholecystitis which turned out to be a perihepatic abscess caused by a dropped migrated appendicolith two and half years following a laparoscopic appendec...

This paper proposes an automatic defect localization and sizing procedure for Structural Health Monitoring based on guided waves imaging. The is applied to aluminum plate equipped with active piezoelectric sensors. strategy obtained through the use of a convolutional neural network trained exclusively numerical simulations wave signals post-processed by delay sum imaging algorithm. shows effect...

OBJECTIVES/HYPOTHESIS Several techniques of endoscopic repair of cerebrospinal fluid (CSF) rhinorrhea were prescribed. Defect localization was mandatory for all. STUDY DESIGN Prospective study. METHODS A prospective study was conducted on nonaccidental CSF rhinorrhea. The sensitivity and specificity of image-guided navigation in localizing the defect were studied. The feasibility and reliab...

OBJECTIVE Ultrasound-guided needle localization has been used prior to the surgical excision of nonpalpable breast lesions. The aim of the study was to assess the feasibility of the use of a saline immersion specimen ultrasound technique (immersion-US) to confirm the successful removal of breast lesions. MATERIALS AND METHODS The devised immersion-US technique was used to examine the excised ...

Note: All policy statements below refer to performing magnetic resonance imaging (MRI) of the breast with contrast and a breast coil. MRI of the breast without a breast coil, regardless of the clinical indication, is considered investigational. See additional comments in Policy Guidelines about the breast imaging team and the need for breast MRI centers to perform MRI-guided biopsy and localiza...

To evaluate the diagnostic eff icacy of breast magnetic resonance imaging (MRI)-guided needle localization and surgical biopsy for suspicious breast lesions occult on physical breast examination, mammography and second-look ultrasound. Twelve patients (age range, 29-68 years; mean 44.9±9.24 years) received breast MR-guided needle localization and surgical biopsy for the suspicious lesions detec...

The optimal screening or treatment strategies of solitary pulmonary nodules especially ground-glass opacities (GGOs) remain controversial. With CT-guided Hookwire localization, it is accurate to find the small lesions during video-assisted thoracoscopic surgery (VATS). In this study, we evaluate the efficiency and safety of CT-guided Hookwire localization of GGO-dominant (GGO component > 50%) p...

BACKGROUND In humans, non-stereotactic frameless neuronavigation systems are used as a topographical tool for non-invasive brain stimulation methods such as Transcranial Magnetic Stimulation (TMS). TMS studies in dogs may provide treatment modalities for several neuropsychological disorders in dogs. Nevertheless, an accurate non-invasive localization of a stimulation target has not yet been per...
