Pulmonary edema It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli. The juxtaphrenic peak sign, also known as diaphragmatic tenting or Kattan sign, refers to the peaked or tented appearance of a hemidiaphragm which can occur in the setting of lobar collapse or post lobectomy (lung).It is caused by retraction of the lower end of diaphragm at an inferior accessory fissure (most common 1), major fissure or inferior pulmonary ligament. Cannonball metastases Radiographic features. Interstitial lung disease (ILD) is an umbrella term that encompasses a large number of disorders that are characterized by diffuse cellular infiltrates in a periacinar location.The spectrum of conditions included is broad, ranging from occasional self-limited inflammatory processes to severe debilitating fibrosis of the lungs. hypopharynx or parapharyngeal space. endotracheal tube Could Call of Duty doom the Activision Blizzard deal? - Protocol Lung cancer (primary lung cancer), or frequently if somewhat incorrectly known as bronchogenic carcinoma, is a broad term referring to the main histological subtypes of primary lung malignancies that are mainly linked with inhaled carcinogens, with cigarette smoke being a key culprit. Right middle lobe collapse Right ventricular enlargement (also known as right ventricular dilatation (RVD)) can be the result of a number of conditions, including:. It is classified as a subtype of interstitial lung disease. Vertebra Radiographic features. The aortic knob should be clearly seen. They may be inserted by medical, surgical, anesthetic/ICU, or radiology specialists. Silhouette From the frontal projection, the cardiac silhouette can be divided into right and left borders: Presentation tends to be with progressive shortness of breath and chronic cough 4.Inspiratory crackles are The French terms "envole de ballons" and "lcher de ballons", which translate to "balloons release", are also used to describe this same appearance.Metastases with such an appearance are classically secondary to 1,2: It has a variety of underlying causes, with a common etiology of chronic inflammation. adenocarcinoma; lymphoma Bronchiectasis Pulmonary metastases typically appear as multiple, peripheral, rounded nodules scattered throughout both lungs 1. Atelectasis can be subcategorised based on underlying mechanism, as follows: resorptive (obstructive) atelectasis Interstitial lung Some report cardiothoracic ratio as a percentage, however this is incorrect, as it is a ratio. The most widely used and most predictive histological nuclear grading system for renal cell carcinoma is the "Fuhrman nuclear grade". The aim of each classification approach is to help identify possible underlying causes together with other accompanying radiological and clinical findings. Juxtaphrenic peak sign Allergic bronchopulmonary aspergillosis Central venous catheter The system is similar to the Fleischner criteria but designed for the subset of patients intended for low-dose As such it is a subtype of atelectasis (collapse is not entirely synonymous with atelectasis, which is a more generic term for 'incomplete expansion'). pulmonary valve stenosis; pulmonary arterial hypertension; atrial septal defect (ASD) ventricular consolidation head and neck: 5%. Other causes include: pulmonary malignancy. Grading. Typically the centrilobular nodules are 2-4 mm in diameter and peripheral, within 5 mm of the pleural surface. from soft tissues: 90-95%. CNS. The differential attenuation of x-ray photons by two adjacent structures defines the silhouette, e.g. Some report cardiothoracic ratio as a percentage, however this is incorrect, as it is a ratio. There are two major types of cardiac conduction devices: pacemakers and automatic implantable cardioverter-defibrillators Open Access Usual interstitial pneumonia (UIP) is a histopathologic and radiologic pattern of interstitial lung disease, which is the hallmark pattern for idiopathic pulmonary fibrosis (IPF).. On imaging, usual interstitial pneumonia usually presents with a lung volume loss and an apicobasal gradient of peripheral septal thickening, bronchiectasis, and honeycombing. by fluid) and thus enlargement The aim of each classification approach is to help identify possible underlying causes together with other accompanying radiological and clinical findings. The list of causes of consolidation is broad but for complete consolidation of a lobe, the most common cause is pneumonia.

Endotracheal tubes (ETT) are wide-bore plastic tubes that are inserted into the trachea to allow artificial ventilation. Tubes come in a variety of sizes and have a balloon at the tip to ensure that gastric contents are not aspirated into the lungs.Adult tubes are usually approximately 1 cm in diameter. Silicosis Air bronchograms will not be visible if the bronchi themselves are opacified (e.g. This situation is exacerbated by at least one well-known PACS vendor using percentages for their inbuilt ratio measurement. The aim of each classification approach is to help identify possible underlying causes together with other accompanying radiological and clinical findings. Lung-RADS (Lung Imaging Reporting and Data System), is a classification proposed to aid with findings in low-dose CT screening exams for lung cancer.The goal of the classification system is to standardize follow-up and management decisions.

Air space opacification is a descriptive term that refers to the filling of the pulmonary tree with material that attenuates x-rays more than the surrounding lung parenchyma.. Air bronchogram refers to the phenomenon of air-filled bronchi (dark) being made visible by the opacification of surrounding alveoli (grey/white). Central venous catheters (CVC), also known as central venous lines (CVL), refer to a wide range of catheters that are inserted so that their distal tips lie in a central vein.Central venous access devices can broadly be divided into four categories. Accessory fissures of the lung usually occur at the borders of bronchopulmonary segments.They are common normal variants but are less commonly seen on imaging.
