It is unclear what role pretreatment tumor vascularity plays in determining outcomes after yttrium-90 radioembolization. A hypothesis was tested that radiographic vascularity of a tumor does not affect patient survival.In this two-institution retrospective study, 137 patients with metastatic liver disease underwent (90)Y radioembolization. Primary sites were categorized as colon, neuroendocrine, and other. All patients underwent triphasic contrast-enhanced computed tomography (CT) or magnetic resonance ...

Angiographic endpoints for chemoembolization of hepatocellular carcinoma (HCC) are subjective, and optimal endpoints remain unknown. Transcatheter intraarterial perfusion (TRIP) magnetic resonance (MR) imaging, when performed in a combined MR/interventional radiology (MR-IR) suite, offers an objective method to quantify intraprocedural tumor perfusion changes, but was previously limited to two spatial dimensions. This study prospectively tested the hypothesis that a new volumetric acquisition over time, ...

Objective: To assess the incidence of clinical and imaging radiation pneumonitis (RP) in a cohort of patients treated with >30 Gy cumulative lung dose (CLD) using Y90 microspheres. Materials and Methods: Four hundred three patients were treated with Y90 microspheres during a 4-year period. Of these, 58 patients received >30 Gy CLD. Patients were followed for toxicities suggestive of imaging or clinical RP. Toxicities were graded using the Radiation Therapy Oncology Group/European Organisation for Research ...

We present the correlation between radiologic and pathologic findings in HCC patients who underwent radioembolization with yttrium-90 ((90)Y) microspheres prior to resection or transplantation. Thirty-five patients with a total of 38 lesions who underwent liver explantation after (90)Y radioembolization were studied. Imaging surrogates following treatment were evaluated; the explants were examined for assessment of necrosis by pathology. The correlation between radiologic and histologic findings of ...

Radioembolization with yttrium 90 (90Y) microspheres represents an emerging transarterial therapy for the treatment of liver malignancies that continues to generate interest in the medical community. The classic indication of treatment response is a reduction in tumor size; however, parenchymal changes (eg, necrosis, lack of enhancement, specific findings at positron emission tomography and functional magnetic resonance imaging) and other benign findings (pleural effusions, perivascular edema, contralateral ...

Understanding the effect of radiation on tissue, the principles of dosimetry and fractionation have led to the acceptance and adoption of radiation as a standard treatment option for cancer. Delivered in staged and scheduled aliquots, radiation will break nucleic strands and cause cellular death. In general, radiation therapies are delivered using external techniques (external beam and intensity-modulated therapy). One of the limitations of such external techniques is that of nontarget radiation. ...

Electropermeabilization involves the application of electrical pulses to increase cell membrane permeability. The purpose of our study was to demonstrate the potential to use electroporation-mediated transcatheter arterial chemoembolization (E-TACE) approaches to increase liver tumor drug uptake while using magnetic resonance imaging (MRI) for intraprocedural optimization of these procedures.Fourteen VX2 tumors were grown in the left hepatic lobes of 8 rabbits. Two tumors were grown in each of 6 rabbits ( ...

Placement of retrievable inferior vena cava filters has seen rapid growth since their introduction into clinical practice. When retrieved, these devices offer the notional benefit of temporary protection from pulmonary embolism related to lower extremity deep venous thrombosis, and mitigation of filter-related deep venous thrombosis. When promptly removed after the indication for mechanical prophylaxis is no longer present, standard endovascular retrieval techniques are frequently successful. However, ...

OBJECTIVE. Utilization of retrievable inferior vena cava filters (rIVCFs) has come under increased scrutiny because of historically high rates of placement, generalized lack of retrieval when the inferior vena cava filter (IVCF) is no longer indicated, and reports of device-related complications. These events have led to an increased interest in IVCF retrieval, including the development of advanced endovascular retrieval techniques and the proliferation of specialized clinical practices for rIVCFs. ...

We introduce a family of solid-state NMR pulse sequences that generalizes the concept of second averaging in the modulation frame and therefore provides a new approach to perform magic angle spinning dipolar recoupling experiments. Here, we focus on two particular recoupling mechanisms—cosine modulated rotary resonance (CMpRR) and cosine modulated recoupling with isotropic chemical shift reintroduction (COMICS). The first technique, CMpRR, is based on a cosine modulation of the rf phase and yields ...

Several human diseases are associated with the formation of amyloid aggregates, but experimental characterization of these amyloid fibrils and their oligomeric precursors has remained challenging. Experimental and computational analysis of simpler model systems has therefore been necessary, for instance, on the peptide fragment GNNQQNY7−13 of yeast prion protein Sup35p. Expanding on a previous publication, we report here a detailed structural characterization of GNNQQNY fibrils using magic angle ...
