Clinical Features and Outcomes of Pulmonary Artery Sarcoma.

Objectives: A retrospective cohort study was designed to describe the clinical features and outcomes of pulmonary artery sarcoma (PAS).

Methods: Twenty-two (22) consecutive patients diagnosed with PAS by pathological examination were enrolled and followed up until they died or until January 2020. The medical records were retrospectively reviewed to evaluate the clinical characteristics, image findings, and outcomes.

Value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography in the evaluation of pulmonary artery activity in patients with Takayasu's arteritis.

Aims: To explore the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the detection of active pulmonary artery (PA) lesions in patients with Takayasu's arteritis (TA).

Methods And Results: Consecutive TA patients with PA involvement were prospectively recruited. Clinical activity was assessed according to the National Institutes of Health (NIH) criteria.

Differential Diagnosis of Pulmonary Artery Sarcoma and Central Chronic Pulmonary Thromboembolism Using CT and MR Images.

Background: Clinical and imaging manifestations are similar in pulmonary artery sarcomas (PAS) and thromboembolic diseases, especially central chronic pulmonary thromboembolism (CPTE). The feasibility of utilising clinical imaging tools such as computed tomography (CT) and magnetic resonance imaging (MRI) for differential diagnosis of PAS and CPTE has not been fully explored, especially MRI.

Methods: Patients with PAS (n=18) and central CPTE (n=20) treated at our hospital between January 2013 and September 2016 were identified retrospectively.

A Case of Pulmonary Hypertension Due to Fistulas Between Multiple Systemic Arteries and the Right Pulmonary Artery in an Adult Discovered for Occulted Dyspnoea.

Background: Pulmonary hypertension (PH) can be caused by a fistula between the systemic and pulmonary arteries. Here, we report a case of PH due to multiple fistulas between systemic arteries and the right pulmonary artery where the ventilation/perfusion scan showed no perfusion in the right lung.

Methods: A 32-year-old male patient was hospitalised for community-acquired pneumonia.

[Early diagnosis of wheat stripe rust and wheat leaf rust using near infrared spectroscopy].

In the present study, near-infrared reflectance spectroscopy (NIRS) technology was applied to implement early diagnosis of two kinds of wheat rusts, i. e. wheat stripe rust and wheat leaf rust, by detecting wheat leaves as disease symptom has not appeared.

A septal angle measured on computed tomographic pulmonary angiography can noninvasively estimate pulmonary vascular resistance in patients with chronic thromboembolic pulmonary hypertension.

Purpose: To explore the correlation between a septal angle measured on computed tomographic pulmonary angiography (CTPA) and pulmonary vascular resistance (PVR) determined by right heart catheterization in patients with chronic thromboembolic pulmonary hypertension (CTEPH).

Materials And Methods: Eighty-six patients with CTEPH (54 men, mean age: 53.08±12.

[Relationship between spinal ventricular septal angle by computer tomographic pulmonary angiography and right cardiac functions, N-terminal brain natriuretic peptide in chronic thromboembolic pulmonary hypertension].

Objective: To explore the relationship of spinal ventricular septal angle (SVSA) measured by computer tomographic pulmonary angiography (CTPA) and right cardiac functions, N-terminal brain natriuretic peptide (NT-proBNP) in the patients with chronic thromboembolic pulmonary hypertension (CTEPH).

Methods: Forty-four CTEPH patients, 26 males and 18 females aged (52 ± 12) years old on average, at our hospital from January 2008 to January 2010 were retrospectively reviewed. SVSA and such pulmonary artery obstruction indices as Qanadli and Mastora indices were evaluated by two independent radiologists.

[Disease index inversion of wheat stripe rust on different wheat varieties with hyperspectral remote sensing].

It is becoming more and more important to use mixed wheat varieties to control wheat stripe rust. Different wheat varieties were planted in field and stripe rust was caused by artificial inoculation. Disease index (DI) was assessed and the canopy reflection data of wheat canopy were obtained by ASD FieldSpec HandHeld FR(325-1 075 nm) made by ASD Company.

[The acute effects of inhaled iloprost on hemodynamics and oxygenation in chronic thromboembolic pulmonary hypertension].

Objective: To evaluate the acute effects of inhaled iloprost on hemodynamics and oxygenation in chronic thromboembolic pulmonary hypertension (CTEPH).

Methods: A prospective study was made. Eighteen patients with CTEPH were enrolled.

[The oxygen kinetic effect of inhaled iloprost in pulmonary artery hypertension and chronic thromboembolic pulmonary hypertension].

Objective: To study the acute oxygen kinetic effect of inhaled iloprost in pulmonary artery hypertension and chronic thromboembolic pulmonary hypertension.

Methods: Twenty-two and 24 patients who were admitted to our hospital between June 2006 and January 2009 with confirmed diagnosis of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) respectively were enrolled to this study. During right heart catheterization, the hemodynamics and oxygen kinetics were monitored at baseline and after inhaling Iloprost (20 micrograms).

[Application of hyperspectral data to the classification and identification of severity of wheat stripe rust].

[The clinical application of electron beam tomography in the diagnosis of pulmonary thromboembolism].

Objective: To evaluate the clinical significance of electron beam computerized tomography (EBCT) in the diagnosis and differential diagnosis of pulmonary thromboembolism (PTE).

Methods: EBCT was performed before March 2004 in 114 consecutive patients with clinically suspected pulmonary vascular diseases, including 76 patients with PTE, 29 with pulmonary arteritis, 5 with primary pulmonary arterial tumor, and 4 with pulmonary arterial invasion by lung or mediastinal carcinoma. EBCT was performed using Imatron C-150 scanner with enhanced continuum volume scan (CVS).
