Metastatic pulmonary calcification (MPC) is a rare lesion, characterized by calcium salt depositing in normal lung tissue and can be caused by a large spectrum of benign and malignant conditions , allowing for the efflux of protein-rich fluid from the capillaries into the lung
Uremic lung: new insights into a forgotten condition Paul J. Scheel1, Manchang Liu1 and Hamid Rabb1 The high mortality rate of acute kidney injury (AKI) despite advances in dialysis led to a renewed appreciation of the impact of AKI on distant organ dysfunction. Mechanistic studies demonstrated that AKI induce The CT findings of UIP are heterogeneous, with regions of fibrotic lung alternating with regions of normal lung. Characteristic CT features of UIP include reticular opacities, honeycombing, and traction bronchiectasis with a basal and peripheral predilection associated with lower lobe volume loss (Figs. 1A and 1B) Uremic pneumonitis is included in the adult respiratory distress syndrome. Diffuse alveolo-capillary damage, interstitial and intraalveolar edema, widespread atelectases, alveolar haemorrhages and pulmonary hyaline membranes are characteristic but not pathognomonic findings in uremic pneumonitits Uremic encephalopathy on CT typically presents as confluent bilateral hypodensity involving the basal ganglia, thalamus and midbrain. The anatomical boundaries between the deep subcortical gray matter typically appear obliterated 10 Hemolytic uremic syndrome (HUS) is a multisystem thrombotic microangiopathic disease characterized by the triad of renal failure, hemolytic anemia and thrombocytopenia. It is the most common cause of renal failure in infancy and childhood requiring dialysis. There are two forms of this syndrome: typical or D+ HUS: corresponds to >90% of all.
The CT images were retro- spectively evaluated by one radiologist. In all cases, any parenchymal (lung), pleural, mediastinal, vascular, and thoracic wall abnormali- ties considered to be related to long-term hemo- dialysis therapy were assessed. Ground-glass opa- city was defined as a region of increased lung attenu Normal Anatomy. CT and MR imaging provide excellent visualization of the pericardium in most patients (, 6 7).The thickness of the normal pericardium, measured on CT scans and on MR images, is less than 2 mm (, Fig 1) (, 8 9).Discrimination of the pericardium from the myocardium on radiologic images requires the presence of epicardial fat or pericardial fluid
At chest radiography and CT, postobstructive pulmonary edema typically manifests as septal lines, peribronchial cuffing, and, in more severe cases, central alveolar edema (, Fig 10). These findings are similar to those in pressure edema. Cardiac size is usually normal, indicating a pressure edema that is not related to overhydration The Society of Cardiovascular Computed Tomography and the Society of Thoracic Radiology issued guidelines in 2016 for reporting CAC on non-contrast-enhanced noncardiac chest CT examinations . These guidelines recommend reporting CAC in all patients irrespective of the scan indication or the patient risk status No organ in the chest is spared the negative effects of uremia. The dialytic treatment itself is often associated with a large array of thoracic complications. We review the main thoracic manifestations of the terminal uremia from the radiological point of view, such as: uremic pleuritis and pericarditis, uremic pneumonia, renal osteodystrophy, infections, and metastatic pulmonary calcifications • Roentgenograms of the chest in cases of so-called pulmonary azotemia, uremic lung, and uremic pneumonia show bilaterally symmetrical densities in the central lung fields with comparatively clear peripheral zones. The latter have been assumed, in the past, to be characteristic of the lung in uremia.. Two experienced chest radiologists (17 and 6 years of experience in interpretation of clinical chest CT scans) analyzed the CT findings, and decisions were reached by consensus. The radiologists were blinded to the pathologic results and to the presence of an underlying malignant tumor
Cardiac CT scans use X-rays to create images of your heart and chest. The test can be used to look for thickening that may be a sign of constrictive pericarditis. Your doctor may order this test to rule out other causes of sudden chest pain, such as a blood clot in a lung (pulmonary embolus) or a tear in your aorta (aortic dissection) Extensive clinical use has confirmed that tacrolimus is a key option for immunosuppression after transplantation [1-3].Tacrolimus as primary immunosuppressant for lung transplant recipient is associated with similar survival and reduction in acute rejection episodes compare with cyclosporine .Haemolytic uraemic syndrome due to cyclosporin or tacrolimus in a lung transplant population is rare Lung Cancer 1.

When Gasser et al first described hemolytic uremic syndrome (HUS) in 1955, it was usually a fatal illness. HUS typically appeared in early childhood and included the combination of Coombs-negative (nonimmune) thrombocytopenic microangiopathic hemolytic anemia and irreversible acute renal failure The CT imaging findings of patients' lungs are shown in Table 4. The main lung imaging features were ground-glass opacity, consolidation, and stripe shadows. A few patients showed pleural effusion and latticed shadows. One patient had negative results in the imaging examination. Table 4 Lung segmentation is an important ﬂrst step for quantitative lung CT im-age analysis and computer aided diagnosis. However, accurate and automated lung CT image segmentation may be made di-cult by the presence of the abnormalities. Since many lung diseases change tissue density, resulting in intensity changes in th
For measuring tumor size, the CT images from the PET/CT scan were assessed using a window level of 2600 HUs with a window width of 1,700 HUs for the lung window and a window level of 25 HUs with a window width of 350 HUs for the mediastinal windows.

Hemolytic-uremic syndrome (HUS) is a clinical syndrome characterized by the triad of thrombocytopenia, microangiopathic hemolytic anemia (MAHA) and acute renal failure. This rare, life threatening. Therefore, earlier detection of lung cancer with low-dose computed tomography (CT) lung cancer screening became a focus of research in radiology. The National Lung Screening Trial (NLST) was the largest randomized controlled trial to demonstrate a significant reduction in lung cancer specific and all-cause mortality with CT screening (Team. established for CT lung damage by using a dichotomous toxicity endpoint for lung density increase.

Metastatic calcification has been associated with multiple-myeloma-induced hypercalcemia. Despite of a relatively high prevalence of metastatic pulmonary calcification in patients with multiple myeloma, only a few cases have been clinically and radiologically detected. A 45-year-old Hispanic male presented to the Emergency Department with complaint of worsening weakness and myalgia Normal chest x ray. Radiological anatomy is where your human anatomy knowledge meets clinical practice. It gathers several non-invasive methods for visualizing the inner body structures. The most frequently used imaging modalities are radiography (X-ray), computed tomography (CT) and magnetic resonance imaging (MRI).X-ray and CT require the use of ionizing radiation while MRI uses a magnetic. Chest pain is the most common symptom of pericarditis. It usually feels sharp or stabbing. However, some people have dull, achy or pressure-like chest pain. The pain usually occurs behind the breastbone or in the left side of your chest. It may spread to your left shoulder and neck. It often gets worse when you cough, lie down or take a deep.
Am Fam Physician. 2002 Nov 1;66 (9):1695-1702. Pericarditis, or inflammation of the pericardium, is most often caused by viral infection. It can also develop as a result of bacterial or other. Survival without fracture was measured at a threshold of 90 HU. HUs (Hounsfield units) are the measure of radiodensity on CT scans. Fracture-free survival was lower in patients with an attenuation level of 90 HU or lower on CT, as well as with DXA T scores of -2.5 or lower. L1-vertebral attenuation levels on CT were correlated with DXA T scores Uremic toxins, such as indoxyl sulfate (IS) and p-cresol, or p-cresyl sulfate (PCS), are markedly accumulated in the organs of chronic kidney disease (CKD) patients. These toxins can induce inflammatory reactions and enhance oxidative stress, prompting glomerular sclerosis and interstitial fibrosis, to aggravate the decline of renal function
CXR and CT examinations were scored for the presence and severity of edema, using a 0-5 scale, and CT HU measurements were obtained in each lobe. Polyserial correlation coefficients evaluated the association between CT HUs and CXR scores, and receiver operating characteristic (ROC) curve analysis determined a cutoff CT HU value for. The pathophysiology of uremic pericarditis is not fully understood. However, there is a correlation observed with levels of blood urea nitrogen (usually >60 mg/dL) and creatinine . In renal failure , the absence or inadequate dialysis can lead to accumulation of these toxins in the body which may cause inflammation of pericardium and. PURPOSE: To develop and validate an automated technique for measuring organ Hounsfield units (HUs) in clinical chest CT images. MATERIALS AND METHODS: An automated computer algorithm was developed to measure the distribution of HUs inside four major organs: the lungs, liver, aorta, and spine
A chest CT scan showed ground-glass opacities bilaterally, baseline laboratory workup showed normal inflammatory markers (C-reactive protein 2.6 mg/L, WBC 3.5 × 10 9 /L, neutrophils 76.2%), normal blood counts (hemoglobin 129 g/L, platelets 223 × 10 12 /L, BUN 5.4 mmol/L), and preserved renal function (creatinine 92 μmol/L). Empiric. Pericarditis is inflammation of the pericardium (the fibrous sac surrounding the heart). Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. Other symptoms of pericarditis can include fever, weakness, palpitations, and shortness.
These include micro-CT, MRI, nuclear imaging (specifically PET and single photon emission computed tomography [SPECT]), and multimodal PET/CT and SPECT/CT scans. For a detailed description of the principles of these techniques and their broader applications in lung imaging, we recommend a recent review article by Gammon and colleagues ( 1 ) The contrast and noncontrast CT scans of 3 patients were registered, and the effect of contrast on the Hounsfield units (HU) was assessed. The effect of contrast was then simulated in the CT scans of 18 patients receiving radiotherapy of the lung by modification of the CT numbers for relevant sections of noncontrast-enhanced CT scans Fibrotic lesions were assessed by quantifying global lung density in HUs by marking the lung parenchyma of every CT slice and calculating total arithmetic mean of HU. Consistent with histological assessment, fibrotic lesions were more prominent between 14 and 21 days after instillation of bleomycin compared with control lungs and improved at 42.

Most of the lung's blood (95%) circulates through low-pressure pulmonary arteries and ends up in the pulmonary capillary bed, where gas is exchanged. About 5% of the blood supply circulates through high-pressure bronchial arteries, which originate at the aorta and supply major airways and supporting structures
