Objective: To study the dosimetric effect on special reconstruction images obtained from an electrocardiograph-gated four-dimensional computed tomography (ECG 4D-CT) series and compare it with the accumulation dose assessment of ECG 4D-CT.Methods: Fifteen patients underwent ECG 4D-CT scans to obtain a 4D-CT series. The 20 phase images of 0–95% were reconstructed at intervals of 5% of the cardiac cycle by the 4D-CT series. The 4D-CT series was specially reconstructed, and the maximum intensity projection (MIP), minimum intensity projection (MinIP), average intensity projection (AIP), and sum intensity projection (SIP)...

CONCLUSION: RT adapted to stage, histology, and resection in multimodal treatment of iL, despite partially decreasing field size (EF to IF), achieves excellent local tumor control and survival rates. The use of modern RT technique and target volume with ISRT offers the option of further reduction of normal tissue complication probability. IMPLICATIONS FOR PRACTICE: Although patients with intestinal lymphoma (iL) are heterogeneous according to histology and subtype, they benefit from radiotherapy. Prospective study data from 134 patients with indolent iL (stage IE-IIE) or aggressive iL (stage IE-IVE) show 100% tumor co...

This study quantitatively compares the fits of boluses designed from different imaging modalities. A head phantom was imaged using three systems: a CT simulator, a 3D optical scanner, and an interchangeable lens camera. Nose boluses were designed and 3D printed from each modality. A 3D printed phantom with air gaps of known thicknesses was used to calibrate mean HU to measure air gaps of unknown thickness and assess the fit of each bolus on the head phantom. The bolus created from the optical scanner data resulted in the best fit, with a mean air gap of 0.16  mm. Smoothing of the CT bolus resulted in a more clinically...

This study analyzes the accuracy of 3D surface mapping with Surface-guided radiation therapy (SGRT) in detecting interfraction setup error and intrafraction motion during SBRT treatments of the lung and abdomen. MATERIALS AND METHODS: Seventy-one patients with 85 malignant thoracic or abdominal tumors treated with SBRT were analyzed. For initial patient setup, an alternating scheme of kV/kV imaging or SGRT was followed by cone beam computed tomography (CBCT) for more accurate tumor volumetric localization. The CBCT six degree shifts after initial setup with each method were recorded to assess interfraction setup error...

An acoustic neuroma, also known as a vestibular schwannoma, is a tumor of the hearing and balance nerve complex in the brain. They are rare, and account for less than 10% of all brain tumors. The tumor involves an area of the brain and ear called the lateral skull base; an acoustic neuroma can range in size, and it can cause a variety of troublesome symptoms related to hearing and balance. It is important to note that although the diagnosis of a brain tumor can cause significant anxiety, acoustic neuromas are noncancerous and grow very slowly. This means that immediate treatment is rarely necessary. What are the most commo...

This study is a multicenter, prospective, single ‐arm, phase II clinical study, and explores the efficacy and tolerability of SRS with anlotinib in NSCLC patients with limited brain metastases. The aim of the study is to provide new treatment options for NSCLC patients with brain metastases.

Recent data from Eastern Cooperative Oncology Group/American College of Radiology Imaging Network 6685 suggests that fluorodeoxyglucose-positron emission tomography/computed tomography offers a sensitive modality for evaluation of lymph node metastasis in the neck, with an overall negative predictive value of 87%, which improved to 94% when a maximum standardized uptake value of 2.5 was used.1 Therefore, we would not recommend a contralateral neck dissection in this patient with a clinically and radiographically contralateral negative neck, particularly given the need for adjuvant radiation and concurrent cisplatin chemotherapy.

We read the article “Solitary plasmacytoma: Lenalidomide-dexamethasone combined with radiation therapy improves progression-free survival and multiple myeloma-free survival” with great interest.1 It offers a combined treatment for solitary plasmacytoma (SP), which has a significant risk of progression to multiple m yeloma (MM). The diagnosis of SP and elimination of MM should include biopsies from the primary lesion and bone marrow (BM), multiparameter flow cytometry, serum and urine electrophoresis, immunoglobulins (Ig), Free Light Chain assay, Bence-Jones proteins, and skeletal survey with magnetic resonance ...
