OBJECTIVE Dorsal arachnoid webs (DAWs) and spinal cord herniation (SCH) are uncommon abnormalities affecting the thoracic spinal cord that can result in syringomyelia and significant neurological morbidity if left untreated. Differentiating these 2 entities on the basis of clinical presentation and radiological findings remains challenging but is of vital importance in planning a surgical approach. The authors examined the differences between DAWs and idiopathic SCH on MRI and CT myelography to improve diagnostic confidence prior to surgery...

Idiopathic pulmonary fibrosis is an interstitial lung disease of unknown etiology resulting in progressive interstitial fibrosis, with a known predilection in West Highland white terriers. In humans, computed tomography (CT) is a standard method for providing diagnostic and prognostic information, and plays a major role in the idiopathic pulmonary fibrosis staging process. Objectives of this retrospective, analytical, cross-sectional study were to establish descriptive criteria for reporting CT findings and test correlations among CT, clinical findings and survival time in West Highland white terriers with idiopathic pulmonary fibrosis...

OBJECTIVE: Both females and the elderly have been identified as vulnerable populations with increased injury and mortality risk in multiple crash scenarios. Particularly in frontal impacts, older females show higher risk to the chest and thorax than their younger or male counterparts. Thoracic geometry plays a role in this increase, and this study aims to quantify key parts of that geometry in a way that can directly inform human body models that incorporate the concept of person age...

REVIEW
John K Field, Michael W Marcus, Matthijs Oudkerk
The National Lung Cancer Screening trial (NLST) demonstrated that individuals assigned to the LDCT screening arm had a 20% lower mortality than those who were assigned to the conventional chest radiography. The NLST was thoroughly analyzed by the US Preventive Task Force on CT Screening and they recommended that lung cancer screening should be implemented. A number of other countries have also recommended implementation, whilst others are awaiting the outcome of the NELSON Trial. However, recommendations for the management of CT screen detected nodules have only recently had any clarity...

Thoracic fluid accumulation is one of the significant and early-stage manifestations of fatal diseases, such as lung-cancer, liver-failure and congestive heart-failure. Currently, computational-tomography (CT)-Scan is the most widely used tool for the detection of thoracic fluid. Yet, it is unable to detect small amounts of fluid, has ionizing radiation and lacks mobility. On the other hand, microwave imaging systems have emerged as an accurate and portable complementary diagnostic tool. However, there is a lack of a complete clinical platform that can fulfill the requirements of accurate and reliable imaging...

Giant cell arteritis ( GCA) is an inflammatory vasculopathy affecting large and middle-sized vessels , specifically cranial arteries derived from carotid artery. Isolated extracranial vessel involvement can occur. Interest in extravascular manifestations is recently increasing because of diffusion of sensitive and specific imaging tools such as 18FDG PET TC . Patients have an increased relative risk of severe infection. Listeria monocytogenes infection risk is increased, and vascular system involvement and graft infection have been, even though rarely, reported...

Ga-PSMA PET/CT was performed in a 68-year-old man to evaluate recurrent prostate cancer due to elevated serum prostate-specific antigen level. Images showed a focal uptake in the prostatic gland, suggesting local relapse, and an intense uptake in the 12th thoracic vertebra, with no morphological abnormalities in CT slices. In order to confirm extraprostatic disease and before radiotherapy planning, a full-spine MRI was performed, resulting with the morphological pattern of a vertebral hemangioma. Hystological analysis confirmed the local relapse in the prostate...

Gastropleural fistula is a relatively rare complication that can be seen as a result of traumatic, nontraumatic, benign, and neoplastic etiologies. Most commonly, these are found in patients with diaphragmatic herniation or prior thoracic surgery. Aortoenteric fistulas are rare communications typically between the abdominal aorta and bowel. We present a rare case of an 88-year-old male who developed a gastropleural fistula with erosions into the wall of the descending thoracic aorta. Computed tomography (CT) is a leading modality in evaluation of suspected gastropleural or aortoenteric fistulas given the quick scan time and widespread availability...

PET/CT is widely used for the evaluation of patients with thoracic malignancies. Although the levels of (18)F-fluorodeoxyglucose (FDG) uptake are usually high in neoplastic diseases, they can also be physiological, due to artifacts. In addition, FDG uptake can occur in benign conditions such as infectious, inflammatory, and iatrogenic lesions. Furthermore, some malignant tumors, such as adenocarcinoma in situ (formerly known as bronchoalveolar carcinoma) and carcinoid tumors, may not show FDG uptake. Here, we illustrate the main pitfalls and artifacts in the interpretation of the results of oncologic PET/CT of the chest, outlining strategies for avoiding misinterpretation...

There is currently an increasing use of magnetic resonance imaging (MRI) as a diagnostic tool in the pediatric population(1). MRI is often viewed as an ideal diagnostic modality because it does not require exposure to ionizing radiation, provides superior soft tissue image quality compared with computed tomography (CT) and is thus well-suited for neurological, musculoskeletal, cardiac, thoracic, and abdominal studies(2). However, MRIs require patient cooperation and extended time periods of immobility, as the studies are often long, loud, and may induce claustrophobia (2-7)...

An abnormal lung shadow was detected in a 39-year-old woman at physical examination and she was followed-up carefully at a nearby hospital. After 5 years follow-up, the patient was referred to our hospital for further examination of the abnormal shadow. A chest computed tomography(CT) scan revealed a 12 mm well-circumscribed nodular shadow in the right lower lobe. A benign tumor such as a hamartoma was suspected preoperatively;video-assisted thoracic surgery was performed for both diagnosis and treatment. Partial resection of the right lower lobe was performed and the tumor was diagnosed as an intrapulmonary solitary fibrous tumor (SFT)...
