Pulmonary Embolism Versus Mimics on Dual-energy Spectral Computed Tomography: An Algorithmic Approach.

Pulmonary embolism is a commonly encountered diagnosis that is traditionally identified on conventional computed tomography angiography. Dual-energy computed tomography (DECT) is a new technology that may aid the initial identification and differential diagnosis of pulmonary embolism. In this review, we present an algorithmic approach for assessing pulmonary embolism on DECT, including acute versus chronic pulmonary embolism, relationship to conventional computed tomography angiography, surrogate for likelihood of hemodynamic significance, and alternative diagnoses for DECT perfusion defects.

CT Coronary Angiography Fractional Flow Reserve: New Advances in the Diagnosis and Treatment of Coronary Artery Disease.

Coronary artery disease (CAD) remains the most common cardiovascular disease, accounting for 6% of all Emergency Department visits and 27% of all Emergency Department hospitalizations. Invasive coronary angiography with fractional flow reserve (FFR) remains the gold standard to assess for hemodynamically stenosis in CAD patients. However, for low- and intermediate-risk patients, noninvasive modalities have started to gain favor as patients with stable CAD who received optimal medical therapy did as well as patients who underwent percutaneous coronary intervention.

Lesser Known Facts of Small Cell Lung Cancer.

Until recently, the treatment of small cell lung cancer (SCLC), a malignancy classically described as having a robust response to first-line therapy with near-universal recurrence, has remained relatively unchanged. Advancements in the management of SCLC have lagged behind those seen for non-small cell lung cancers. As the era of precision medicine and targeted immunotherapy evolves, radiologists must be familiar with the modern treatment paradigms of SCLC and associated imaging patterns, including classic and nonclassic appearances of treatment complications.

"-Omas" presenting as "-itis": acute inflammatory presentations of common gastrointestinal neoplasms.

Oncologic emergencies have a high rate of morbidity and mortality. This review covers several scenarios of gastrointestinal malignancies presenting emergently as various acute abdominal pathologies. Radiologists should be familiar with the typical imaging findings, clinical presentations, and laboratory values which may suggest a background neoplasm, particularly when encountered in the context of an acute inflammatory state.

Serum tumor markers and testicular germ cell tumors: a primer for radiologists.

Serum tumor markers (STMs) play a critical role in the diagnosis, staging and follow-up of both seminomatous and nonseminomatous testicular germ cell neoplasms. Levels of alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactate dehydrogenase (LDH), especially those measured after orchiectomy, also have implications for patient prognosis. Given that testicular germ cell tumors represent the most common solid tumor in men aged 20-34, radiologists must have familiarity with the clinical utilization and implications of these STMs.

The Role of Extra-Articular Tenodesis in Combined ACL and Anterolateral Capsular Injury.

Background: The "gold standard" treatment of anterolateral capsular injuries in anterior cruciate ligament (ACL)-deficient knees has not been determined. The purpose of this study was to determine the effects of ACL reconstruction and extra-articular reconstruction on joint motion in the ACL-deficient knee and in the combined ACL and anterolateral capsule-deficient knee.

Methods: An anterior tibial load of 134 N and internal tibial torque of 7 Nm were applied to 7 fresh-frozen cadaveric knees using a robotic testing system continuously throughout the range of flexion.

Anatomic and Histological Investigation of the Anterolateral Capsular Complex in the Fetal Knee.

Background: There is currently disagreement with regard to the presence of a distinct ligament in the anterolateral capsular complex of the knee and its role in the pivot-shift mechanism and rotatory laxity of the knee.

Purpose: To investigate the anatomic and histological properties of the anterolateral capsular complex of the fetal knee to determine whether there exists a distinct ligamentous structure running from the lateral femoral epicondyle inserting into the anterolateral tibia.

Study Design: Descriptive laboratory study.

Increased lateral tibial posterior slope is related to tibial tunnel widening after primary ACL reconstruction.

Purpose: The purpose of the study was to determine the influence of femoral and tibial bone morphology on the amount of femoral and tibial tunnel widening after primary anatomic ACL reconstruction. It was hypothesized that tibial and femoral bone morphology would be significantly correlated with tunnel widening after anatomic ACL reconstruction.

Methods: Forty-nine consecutive patients (mean age 21.

Anatomical Individualized ACL Reconstruction.

The anterior cruciate ligament (ACL) is composed of two bundles, which work together to provide both antero-posterior and rotatory stability of the knee. Understanding the anatomy and function of the ACL plays a key role in management of patients with ACL injury. Anatomic ACL reconstruction aims to restore the function of the native ACL.

Correlation between a 2D simple image analysis method and 3D bony motion during the pivot shift test.

Background: The pivot shift test is the most specific clinical test to detect anterior cruciate ligament injury. The purpose of this study was to determine the correlation between the 2D simple image analysis method and the 3D bony motion of the knee during the pivot shift test and assess the intra- and inter-examiner agreements.

Methods: Three orthopedic surgeons performed three trials of the standardized pivot shift test in seven knees.

Analysis of the influence of anaesthesia on the clinical and quantitative assessment of the pivot shift: a multicenter international study.

Purpose: The main goal of this work was to evaluate the pivot shift test in awake and anesthetized patients by using two different quantitative methodologies and comparing the results with the standard clinical grading, taking advantage of a multicenter international study.

Methods: Patients between 16 and 50 years of age undergoing primary unilateral single-bundle anterior cruciate ligament (ACL) reconstruction were considered eligible. The pivot shift test was performed pre-operatively, with the patient awake and again with the patient under general anaesthesia.

Tensile properties of a split quadriceps graft for ACL reconstruction.

Purpose: Anatomic double-bundle ACL reconstruction can be performed using different grafts, such as quadriceps tendon. Grafts can be split in either coronal or sagittal planes to approximate the two bundles of the native ACL, but it is unknown whether a difference exists in the graft tensile properties depending on splitting plane. The purpose of this study was to evaluate the tensile properties of split human quadriceps tendon-bone grafts.

Development of computer tablet software for clinical quantification of lateral knee compartment translation during the pivot shift test.

The pivot shift test is a commonly used clinical examination by orthopedic surgeons to evaluate knee function following injury. However, the test can only be graded subjectively by the examiner. Therefore, the purpose of this study is to develop software for a computer tablet to quantify anterior translation of the lateral knee compartment during the pivot shift test.

Graft maturity of the reconstructed anterior cruciate ligament 6 months postoperatively: a magnetic resonance imaging evaluation of quadriceps tendon with bone block and hamstring tendon autografts.

Purpose: The purpose of this study was to report the potential differences associated with graft maturity measured on magnetic resonance imaging (MRI) between quadriceps tendon with bone block and hamstring tendon autografts 6 months after ACL reconstruction.

Methods: Twenty-six patients (15 male, 11 female; mean age 29.4 ± 17 years, range 13-46 years) who had undergone anatomic SB ACL reconstruction with either hamstring or quadriceps tendon with bone block autografts and had postoperative MRI 6 months after surgery.
