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...

Aspergillus empyema is usually reported as a complication of surgical procedures, and spontaneous cases are quite rare. Here, we describe the case of a 16-year-old man who suddenly developed dyspnea despite previously being healthy. Chest computed tomography showed multiple mass-containing cavity lesions, pneumothorax, and pleural effusion in the left thorax. Within 2 weeks, Aspergillus fumigatus grew from his pleural effusion, thus he was diagnosed with Aspergillus empyema. He also developed severe eosinophilia after admission, and was treated with anti-fungal drugs...

Patient with Pancoast Tumor usually present in advanced stage of the disease which requires chemotherapy and radiotherapy as options of treatment. Histologic confirmation is a key for further treatment of these patients. Normally in bronchoscopy the lesion can't be visualised and in result making biopsy difficult to perform. Transthoracic biopsy through computed tomography poses anatomic difficulties and not always the pulmonary lesion can be reached. We report a case of pancoast tumor in a 68 year old male who presented with left arm pain and upper lobe increased density mass in chest x ray...

Mycoplasma pneumoniae is an atypical bacterium that most commonly causes upper respiratory tract infections, but it can also cause pneumonia, referred to as "walking pneumonia." Although cavitary lesions are present in a wide variety of infectious and noninfectious processes, those attributable to M. pneumoniae are extremely uncommon; thus, to date, epidemiological studies are lacking. Here, we present a rare case of a 20-year-old male, referred to us from a psychiatric facility for evaluation of a cough, who was found to have a cavitary lesion in the right upper lobe...

BACKGROUND: Skeletal muscle mass decreases in end-stage heart failure and is predictive of clinical outcomes in several disease states. Skeletal muscle attenuation and quantity as quantified on preoperative chest computed tomographic scans may be predictive of mortality after continuous flow (CF) left ventricular assist device (LVAD) implantation. METHODS AND RESULTS: A single-center continuous flow-LVAD database (n=354) was used to identify patients with chest computed tomographies performed in the 3 months before LVAD implantation (n=143)...

BACKGROUND: The nodular bronchiectatic (NB) form of non-tuberculous mycobacteria (NTM) lung disease usually involves the right middle lobe (RML) and the left upper lobe lingular segment. However, the reason underlying this preference is not known. METHODS: Fifty patients with NB NTM lung disease who had both positive NTM culture(s) and NB lesions in the RML or lingular segment on computed tomography (CT) of the chest, and 100 healthy subjects matched for sex, age, height and body weight with normal chest CT, were randomly selected...

BACKGROUND: Studies have demonstrated both positive and negative effects of obesity on clinical outcomes in chronic obstructive pulmonary disease (COPD). In other chronic diseases, fat location is differentially associated with disease outcomes; however, this relationship has not been well studied in COPD. OBJECTIVE: To determine if fat location explains the differential association of body mass index (BMI) with clinical outcome measures in smokers. METHODS: Baseline and 6-year chest computed tomography scans from 68 current and former smokers were used to quantify mediastinal and subcutaneous fat...

We report a rare case of a large mediastinal pancreatic pseudocyst compressing the left atrium and the esophagus and causing dyspnea, palpitations, and emesis. Chest radiograph was non-diagnostic, esophagogastroduodenoscopy showed diffuse extrinsic compression of the distal esophagus and gastric corpus, but a definitive diagnosis was confirmed by computed tomography. We decided to perform surgery due to the recurrence of the pancreatic pseudocyst, a history of unsuccessful radiologically guided external drainage a few years earlier, and a very large diameter of the pseudocyst causing acute cardio-pulmonary distress syndrome...

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...

Pulmonary artery thrombosis (PAT) is involved in lung vascular dysfunction during acute chest syndrome (ACS) complicating sickle cell disease (SCD). No clinical score is available to identify patients eligible for multi-detector computed tomography (MDCT) angiography during ACS. This retrospective study aimed to develop a risk score for PAT during ACS (PAT-ACS risk score). Patients with SCD were investigated by MDCT during ACS. A logistic regression was performed to determine independent risks factors for PAT and to build the PAT-ACS risk score...

Congenital cyst adenoid malformation (CCAM) is a rare congenital malformation occurring in approximately 1-4 in 100,000 births. It is classified into five subtypes with type 1 CCAM is most common subtype. The diagnosis of CCAM is usually made in infancy, and it is rare in adolescents and adults. We report a 15-year-old female, who presented in pediatric outpatient department with a history of recurrent cough since infancy. On the basis of clinical examination, provisional diagnosis of asthma was considered and patient was started on inhaled corticosteroid and long-term β2 agonist...

PURPOSE: Historically, the process of positioning a patient prior to imaging verification used a set of permanent patient marks, or tattoos, placed subcutaneously. After aligning to these tattoos, plan specific shifts are applied and the position is verified with imaging, such as cone-beam computed tomography (CBCT). Due to a variety of factors, these marks may deviate from the desired position or it may be hard to align the patient to these marks. Surface-based imaging systems are an alternative method of verifying initial positioning with the entire skin surface instead of tattoos...
