BACKGROUND Synchronous bilateral breast cancer is rare. A case is presented where whole breast irradiation (WBI) was planned after breast conserving surgery in a patient with synchronous bilateral breast cancer. A comparison was made between the feasibility of helical tomotherapy and direct tomotherapy. CASE REPORT A 60-year-old woman was found to have bilateral breast nodules on routine mammographic screening, resulting in bilateral lumpectomy and sentinel lymph node biopsy. Histopathology showed a 6 mm diameter invasive ductal carcinoma in the right breast (Grade 1, hormone receptor positive, HER2 negative) and an 8mm diameter tubular carcinoma in the left breast (Grade 1, hormone receptor positive, HER2 negative)...

Cysticercosis is an important public health problem in developing countries. The major involvement sites are the central nervous system and the eyes, although striated muscles and subcutaneous tissues are frequently involved in the disseminated form of disease. Pulmonary involvement in cysticercosis is very rare and ill-defined nodular shadows distributed throughout the lung is the usual radiological presentation. Only one case of cysticercosis presenting as lung cavity with pleural effusion has been reported so far in literature...

BACKGROUND: Senior surgical residents are of paramount importance in directing further therapeutic modalities based on their interpretation of critical diagnostic imaging. We propose that senior surgical residents are proficient with interpreting radiologic imaging studies in the trauma patient. METHODS: A prospective cohort study was performed comparing surgery resident interpretations of computerized tomography (CT) scans of the head, maxillofacial bones, spine (cervical, thoracic, lumbar), chest, abdomen, pelvis, and chest X-rays versus final radiologists' reports at a level II trauma center from September 2014 to May 2015...

A 56-year-old man presented with a chest computed tomography (CT) finding of a right upper lobe nodule, which was diagnosed using brush cytology as adenocarcinoma stage IB (cT2aN0M0). Repeat CT scan for preoperative evaluation revealed a small, slightly hypodense spot in the pancreatic body, which was diagnosed as pancreatic metastasis from lung cancer using endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB). Because of the presence of distant metastasis, surgical resection was deferred and chemotherapy was chosen instead...

BACKGROUND: ''Cannon ball'' opacities on chest X-rays are a common manifestation of hematogenous dissemination of a malignant tumor in the lungs. They indicate an advanced stage of disease with a very grim prognosis in terms of cure and survival. In aerospace medicine, this aspect means the patient is unfit for flight duties. Nonmetastatic etiologies of pulmonary nodules are rare. We report a case of cannon ball opacities discovered fortuitously during an admission visit. CASE REPORT: A 23-yr-old flight attendant candidate came to the Aeromedical Expertise Center of the Military Hospital in Rabat for medical evaluation...

Chest digital tomosynthesis (DT) has potential advantages compared to computed tomography (CT) such as radiation dose reduction. However, the role of DT in pulmonary nodule management remains investigative. We compared DT against CT for pulmonary nodule detection and size measurement. A clinical population comprising 54 nodules from 30 patients and a screening population comprising 42 nodules from 52 patients were included. Scans were independently read by two radiologists. Agreement in nodule measurements between readers and between modalities was assessed by Bland-Altman analysis using a 95% level of significance...

In a retrospective study performed in non-functioning GEP tumor patients we further investigated (111)In-Pentetreotide SPECT/CT usefulness in diagnosis, staging and follow-up also evaluating whether the procedure may give more information than conventional imaging procedures (CIP), such as CT, MRI, US. We enrolled 104 consecutive patients with non-functioning GEP tumors, 30 in initial diagnosis and staging phases (IDS) and 74 in follow-up (FU). All patients underwent somatostatin receptor scintigraphy (SRS) whole body scan at 4, 24 and, if necessary, 48 hours followed by abdominal and chest SPECT/CT after (111)In-Pentetreotide 148-222 MBq i...

BACKGROUND: A ground-glass nodule (GGN) represents early-stage lung adenocarcinoma. However, there is still no consensus for preoperative staging of GGNs. Therefore, we evaluated the need for the routine use of positron emission tomography/computed tomography (PET)/computed tomography (CT) scans and brain magnetic resonance imaging (MRI) during staging. METHODS: A retrospective analysis was undertaken in 72 patients with 74 GGNs of less than 3 cm in diameter, which were confirmed via surgery as malignancy, at the Samsung Medical Center between May 2010 and December 2011...

PURPOSE: Detailed characterization of changes in vessel size is crucial for the diagnosis and management of a variety of vascular diseases. Because clinical measurement of vessel size is typically dependent on the radiologist's subjective interpretation of the vessel borders, it is often prone to high inter- and intra-user variability. Automatic methods of vessel sizing have been developed for two-dimensional images but a fully three-dimensional (3D) method suitable for vessel sizing from volumetric X-ray computed tomography (CT) or magnetic resonance imaging has heretofore not been demonstrated and validated robustly...

Nocardiosis is a rare but severe infection caused by bacteria of the genus nocardia, which belong to the order actinomycetales. If they can affect immunocompetent adult, nocardioses are pathologies affecting the individuals with weakened immune system. Pulmonary involvement is the most common manifestation, its correct management is based on diagnosis, which is often delayed due to non-specific symptoms and inconclusive specimens. We here report two cases of nocardiosis in immunocompetent patients. The first case concerns a 24-year old man with a history of smoking and alcoholism, hospitalized for chest pain and hemoptysis of low abundance evolving for two months, associated with the occurrence of dorsal subcutaneous fistulized abscess...

Tracheobronchopathia osteochondroplastica (TPO) is a rare pathology characterized by a progressive segmentary stenosis of the respiratory tract due to proliferation of osteocartilagineous nodules in the lumen of the distal part of the trachea and large bronchial trunks. Prognosis is usually benign, but some cases with an acute progression and a lethal outcome have been described. Clinical presentation is non specific, the chest x-ray is generally normal and there are not typical radiological signs of suspicion: diagnosis of TPO is usually incidental...

Lung ultrasound is increasingly being used by the bedside physicians to complement the findings of physical examination. Lung ultrasound is non-invasive, devoid of radiation exposure and can be performed rapidly and repeatedly as needed at bedside. The diagnostic accuracy of lung ultrasound for common conditions like pleural effusion, pneumothorax, pulmonary edema and pneumonia is superior to chest radiograph and is comparable to chest CT scan. Lung ultrasound is helpful to evaluate the progress of lung pathology and response to treatment, over time...

PURPOSE: Our goal is to develop a model-based approach for CT dose estimation. We previously presented a CT dose estimation method that offered good accuracy in soft tissue regions but lower accuracy in bone regions. In this work, we propose an improved physic-based approach to achieve high accuracy for any materials and realistic clinical anatomies. METHODS: Like Monte Carlo techniques, we start from a model or image of the patient and we model all relevant x-ray interaction processes...
