Lung cancer remains the leading cause of cancer-related mortality and is responsible for more deaths than breast, prostate, and colon cancer combined. Most patients are diagnosed with advanced disease at the time of presentation, and treatment options have traditionally included surgery, chemotherapy, and/or radiation. However, significant advances in the molecular characterization of lung cancer have led to the creation of effective immunotherapies that assist in the recognition of cancer as foreign by the host immune system, stimulate the immune system, and relieve the inhibition that allows tumor growth and spread...

In patients with early-stage lung cancer, surgical resection is the treatment of choice. Knowledge of the expected postsurgical changes and awareness of the temporal evolution of these findings as well as potential complications are important in avoiding misinterpretation. We review the surgical techniques used for lung cancer resection, expected postoperative radiologic manifestations, as well as potential early and late postoperative complications in order to improve diagnostic interpretation and optimize patient management...

PURPOSE: The aim of this study was to assess the left ventricular (LV) remodeling response to chemotherapy in low-cardiac-risk women with newly diagnosed nonmetastatic breast cancer. Cardiotoxic effects of chemotherapy are an increasing concern. To effectively interpret cardiac imaging studies performed for screening purposes in patients undergoing cancer therapy it is necessary to understand the normal changes in structure and function that may occur. METHODS: Twenty women without preexisting cardiovascular disease, of a mean age of 50 years, newly diagnosed with nonmetastatic breast cancer and treated with anthracycline or trastuzumab were prospectively enrolled and evaluated at four time points (at baseline, during chemotherapy, 2 weeks after chemotherapy, and 6 months after chemotherapy) using cardiac magnetic resonance imaging, blood samples, and a clinical questionnaire...

PURPOSE: Dual-energy computed tomography (DECT) can be used for visual determination of iodine distribution in the myocardium (iodine image); however, the accuracy and reproducibility of the process remains debatable. Because of the low contrast-to-noise ratio of CT, we hypothesized that quantitative measurement may be more accurate for detecting myocardial ischemia. In this study, we evaluated our quantitative method by comparing it with visual analysis using Tc-tetrofosmin (TF) stress-rest single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) as the reference standard...

Obesity and its association with long-term health problems constitutes one of the major challenges in medicine. Though diet regulation and exercise are the primary treatment strategies, surgery is the most reliable long-term solution. Although bariatric surgical complications continue to decline, prompt recognition is essential to optimize patient outcomes. Despite their relative rarity, it is important to recognize thoracic complications, as several of these can result in severe morbidity and mortality. This article describes common bariatric surgical procedures performed, their expected postoperative appearances, and intrathoracic complications...

Non-electrocardiographic (ECG)-gated computed tomography (CT) of the chest is one of the most commonly performed imaging studies. Although the heart is included in every CT study, cardiac findings are commonly underreported in radiology reports. Left ventricular size is one of the most important prognostic markers in multiple cardiac diseases and can be measured on almost all non-ECG-gated multidetector chest CT studies. This review will discuss the available evidence on different measurements of left ventricular size obtained on non-ECG-gated CT of the chest...

PURPOSE: The aim was to evaluate computed tomography (CT)-measured pulmonary artery diameter (PAD) and lung density as predictors of pulmonary hypertension (PH) in subjects with systemic sclerosis (SSc). We compared these PAD values with normal values and between SSc subgroups with PH and/or interstitial lung disease (ILD). We investigated whether PAD predicts PH and whether lung densitometry, by using the 85th percentile density value (Perc85) as a measure for ILD, can predict PH. MATERIALS AND METHODS: PAD and Perc85 were measured in axial CT scans and compared between 54 SSc and 76 control subjects...

Familiarity with congenital heart disease (CHD) and its manifestations in adults is becoming increasingly important for the practicing cardiothoracic imager. The use of computed tomographic angiography is becoming commonplace not only in adults with a history and subsequent interventions for CHD as a child but also in de novo detection of-typically-milder, survivable forms of CHD, which are clinically suspected because of declining cardiac performance, cardiac events, or murmurs. Occasionally, adult CHD (ACHD) is found incidentally on scans performed for other indications (eg, trauma or neoplasm staging) because of improvements in computed tomographic technology and advanced visualization...

Because of great strides in medical care, survival into adulthood has become a common expectation in patients suffering from nearly all forms of congenital heart disease. As this aging population expands, the utilization of cardiac magnetic resonance imaging in their care continues to grow. Magnetic resonance technology has developed exponentially over the last 2 decades, and several advanced techniques for imaging adults with congenital heart disease have moved from the purely research arena into routine clinical care...

The increasing number of patients with adult congenital heart disease (ACHD) calls for the development of noninvasive imaging techniques that allow a long-term evaluation of native and postsurgical anatomy and function. Echocardiography remains the imaging modality of choice for congenital heart disease, but it is affected by limited acoustic windows and poor tissue characterization. Cardiac computed tomography and cardiac catheter angiography are 2 valid alternatives for the anatomic and functional assessment of ACHD; however, both use ionizing radiation, and cardiac catheter angiography requires an invasive approach...

There has been tremendous growth in the population of adults with congenital heart disease (CHD) over the last few decades because of advances in medical care. Whereas some cases are cured during childhood, most patients instead undergo palliation, which leaves them at risk for late complications. Lifelong clinical follow-up involving serial multimodality imaging is helpful to monitor and guide the treatment of late complications. Imaging of these individuals is challenging because of their unique anatomy and therefore requires careful consideration on a case-by-case basis...

The survival rate of patients with congenital heart disease (CHD) has dramatically improved over the last 2 decades because of technological and surgical advances in diagnosis and treatment, respectively. The vast majority of CHD patients are, in fact, amenable to treatment by either device closure or surgery. Considering the wide spectrum of surgical procedures and complex native and derived anatomy, continuous and detailed follow-up is of paramount importance. Cardiac magnetic resonance and cardiac computed tomography angiography are the cornerstones of diagnosis and follow-up of CHD, allowing for comprehensive noninvasive assessment of the heart, coronary tree, and intrathoracic great vessels, along with both morphological and functional evaluation...

Myocardial T1-mapping has become feasible over the past decade as emerging technological magnetic resonance imaging advances enable increasingly rapid and reliable acquisition techniques. A variety of T1-mapping sequences are in development, with most allowing for the acquisition of a single-slice T1-map in a single breath-hold. The development of these protocols has spurred investigation into a wide range of potential clinical uses, including the characterization of cardiomyopathies. Although native T1-mapping provides superior tissue characterization, postcontrast T1-mapping is still indispensable for extracellular volume quantification...
