Patient Centring in CT: An International Survey of Clinical Practice and Future Directions

Journal of Medical Radiation Sciences, EarlyView.
An international survey of 321 radiographers from 43 countries found vertical mis‐centring below the CT isocentre is the most frequent positioning error. Only 34% had access to automated centring systems and 17% used them consistently. Substantial knowledge gaps exist regarding radiation dose and CT number variability, highlighting the need for ...

Size‐specific dose estimates calculated using patient size measurements from scanned projection radiograph in high‐resolution chest computed tomography

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 85-92, March 2025.
This study established that patient's lateral width measurements made from scanned projection radiograph (SPR) is an overestimate compared to those measured from tomographic slices by about 10%. Size‐specific dose estimates (SSDE) calculated using lateral width measured from SPR correlates well with SSDE calculated using water equivalent diameter of ...

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

International Journal of Climatology, EarlyView.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

International Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence

International Journal of Climatology, EarlyView.
Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Inside the Black Box: Understanding Organizational Decision Making Processes in VC Funds

Strategic Change, EarlyView.
ABSTRACT Organizational decision making within venture capital (VC) funds remains an unexplored “black box” despite its critical role in navigating investment uncertainty. This paper develops a conceptual framework that integrates established theories of organizational decision making and adapts them to the VC context. By synthesizing Buying Center (BC)

Oncoplastic Surgery Versus Total Breast Reconstruction in Locally Advanced and Multicentric Carcinomas. A Matched Comparative Cohort Study of Oncologic and Aesthetic Outcomes

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background/Objective This study aimed to compare extreme oncoplastic surgery (EO‐partial breast reconstruction for tumors > 5 cm or multicentric lesions) with extreme reconstruction (ER‐mastectomy with reconstruction for tumors >5 cm or multicentric lesions).

Timing Matters: A Meta‐Analysis of BREAST‐Q Administration in Tissue‐Expander and Implant‐Based Breast Reconstruction

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background BREAST‐Q is the most widely used patient‐reported outcome measure following breast reconstruction, yet no consensus exists on optimal timing or duration of administration. We analyzed BREAST‐Q follow‐up after implant‐based reconstruction, comparing direct‐to‐implant (DTI) and two‐stage tissue expander (TE), to determine how outcomes
